• Hibernate + PostgreSQL : relation does not exist - SQL Error: 0, SQLState: 42P01

  - by tommy599

  Hello, I am having some problems trying to work with PostgreSQL and Hibernate, more specifically, the issue mentioned in the title. I've been searching the net for a few hours now but none of the found solutions worked for me. I am using Eclipse Java EE IDE for Web Developers. Build id: 20090920-1017 with HibernateTools, Hibernate 3, PostgreSQL 8.4.3 on Ubuntu 9.10. Here are the relevant files: Message.class package hello; public class Message { private Long id; private String text; public Message() { } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getText() { return text; } public void setText(String text) { this.text = text; } } Message.hbm.xml <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="hello"> <class name="Message" table="public.messages"> <id name="id" column="id"> <generator class="assigned"/> </id> <property name="text" column="messagetext"/> </class> </hibernate-mapping> hibernate.cfg.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">org.postgresql.Driver</property> <property name="hibernate.connection.password">bar</property> <property name="hibernate.connection.url">jdbc:postgresql:postgres/tommy</property> <property name="hibernate.connection.username">foo</property> <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property> <property name="show_sql">true</property> <property name="log4j.logger.org.hibernate.type">DEBUG</property> <mapping resource="hello/Message.hbm.xml"/> </session-factory> </hibernate-configuration> Main package hello; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration; public class App { public static void main(String[] args) { SessionFactory sessionFactory = new Configuration().configure() .buildSessionFactory(); Message message = new Message(); message.setText("Hello Cruel World"); message.setId(2L); Session session = null; Transaction transaction = null; try { session = sessionFactory.openSession(); transaction = session.beginTransaction(); session.save(message); } catch (Exception e) { System.out.println("Exception attemtping to Add message: " + e.getMessage()); } finally { if (session != null && session.isOpen()) { if (transaction != null) transaction.commit(); session.flush(); session.close(); } } } } Table structure: foo=# \d messages Table "public.messages" Column | Type | Modifiers -------------+---------+----------- id | integer | messagetext | text | Eclipse console output when I run it Apr 28, 2010 11:13:53 PM org.hibernate.cfg.Environment <clinit> INFO: Hibernate 3.5.1-Final Apr 28, 2010 11:13:53 PM org.hibernate.cfg.Environment <clinit> INFO: hibernate.properties not found Apr 28, 2010 11:13:53 PM org.hibernate.cfg.Environment buildBytecodeProvider INFO: Bytecode provider name : javassist Apr 28, 2010 11:13:53 PM org.hibernate.cfg.Environment <clinit> INFO: using JDK 1.4 java.sql.Timestamp handling Apr 28, 2010 11:13:53 PM org.hibernate.cfg.Configuration configure INFO: configuring from resource: /hibernate.cfg.xml Apr 28, 2010 11:13:53 PM org.hibernate.cfg.Configuration getConfigurationInputStream INFO: Configuration resource: /hibernate.cfg.xml Apr 28, 2010 11:13:53 PM org.hibernate.cfg.Configuration addResource INFO: Reading mappings from resource : hello/Message.hbm.xml Apr 28, 2010 11:13:54 PM org.hibernate.cfg.HbmBinder bindRootPersistentClassCommonValues INFO: Mapping class: hello.Message -> public.messages Apr 28, 2010 11:13:54 PM org.hibernate.cfg.Configuration doConfigure INFO: Configured SessionFactory: null Apr 28, 2010 11:13:54 PM org.hibernate.connection.DriverManagerConnectionProvider configure INFO: Using Hibernate built-in connection pool (not for production use!)

Everything is lowercase, so I don't think that it's that issue. If I switch to MySQL, the same code same project (I only change driver,URL, authentication), it works. In Eclipse Datasource Explorer, I can ping the DB and it succeeds. Weird thing is that I can't see the tables from there either. It expands the public schema but it doesn't expand the tables. Could it be some permission issue? Thanks!

• Can't store array in json field in postgresql (rails) can't cast Array to json

  - by Drew H

  This is the error I'm getting when I run db:migrate rake aborted! can't cast Array to json This is my table class CreateTrips < ActiveRecord::Migration def change create_table :trips do |t| t.json :flights t.timestamps end end end This is in my seeds.rb file flights = [{ depart_time_hour: 600, arrive_time_hour: 700, passengers: [ { user_id: 1, request: true } ] }] trip = Trip.create( { name: 'Flight', flights: flights.to_json } ) For some reason I can't do this. If I do this. trip = Trip.create( { name: 'Flight', flights: { flights: flights.to_json } } ) It works. I don't want this though because now I have to access the json array with trip.flights.flights. Not the behavior I'm wanting.

• Learning PostgreSql: polymorphism

  - by Alexander Kuznetsov

  Functions in PL/PgSql are polymorphic, which is very different from T-SQL. Demonstrating polymorphism For example, the second CREATE FUNCTION in the following script does not replace the first function - it creates a second one: CREATE OR REPLACE FUNCTION public .GetQuoteOfTheDay ( someNumber INTEGER ) RETURNS VARCHAR AS $body$ BEGIN RETURN 'Say my name.' ; END ; $body$ LANGUAGE plpgsql ; CREATE OR REPLACE FUNCTION public .GetQuoteOfTheDay ( someNumber REAL ) RETURNS VARCHAR AS $body$ BEGIN RETURN...(read more)

• C++ linking error when linking postgresql

  - by Brent Rowswell

  When compiling my code I run into an issue as follows: io.cpp:21: undefined reference to `PQconnectdb' as well as all other instances of missing postgres function calls occurring in my code. Obviously this is a linking problem, I'm just not sure what the link issue is. I'm compiling with the following: mpiCC -c -O2 -g -Wall -Werror -I /usr/include/postgresql/ decisioning_mpi.cpp g++ -c -O2 -g -Wall -Werror -I /usr/include/postgresql/ io.cpp g++ -c -O2 -g -Wall -Werror -I /usr/include/postgresql/ calculations.cpp g++ -c -O2 -g -Wall -Werror -I /usr/include/postgresql/ rules.cpp g++ -c -O2 -g -Wall -Werror -I /usr/include/postgresql/ Instrument.cpp g++ -c -O2 -g -Wall -Werror -I /usr/include/postgresql/ Backtest_Parameter_CPO.cpp g++ -c -O2 -g -Wall -Werror -I /usr/include/postgresql/ Backtest_Trade_CPO.cpp g++ -c -O2 -g -Wall -Werror -I /usr/include/postgresql/ Data_Bar.cpp mpiCC -o decisioning_mpi -O2 -g -Wall -Werror -L/usr/lib -lm -lpq decisioning_mpi.o io.o calculations.o rules.o Instrument.o Backtest_Parameter_CPO.o Backtest_Trade_CPO.o Data_Bar.o It should be noted that this is the correct directory for libpq-fe.h and that I'm linking pq, so I'm not exactly sure why the postgres functions aren't linking correctly. I'm running Ubuntu 12.04 and installed psql (PostgreSQL) 9.1.6 from synaptic. As well I'll short circuit this, I am using #include "libpq-fe.h". Any ideas on how I can get this linking issue resolved?

• Large ResultSet on postgresql query

  - by tuler

  I'm running a query against a table in a postgresql database. The database is on a remote machine. The table has around 30 sub-tables using postgresql partitioning capability. The query will return a large result set, something around 1.8 million rows. In my code I use spring jdbc support, method JdbcTemplate.query, but my RowCallbackHandler is not being called. My best guess is that the postgresql jdbc driver (I use version 8.3-603.jdbc4) is accumulating the result in memory before calling my code. I thought the fetchSize configuration could control this, but I tried it and nothing changes. I did this as postgresql manual recomended. This query worked fine when I used Oracle XE. But I'm trying to migrate to postgresql because of the partitioning feature, which is not available in Oracle XE. My environment: Postgresql 8.3 Windows Server 2008 Enterprise 64-bit JRE 1.6 64-bit Spring 2.5.6 Postgresql JDBC Driver 8.3-603

• PostgreSQL update problems with uuid

  Hi, I am trying to run yum update on my CentOS 5.2 box and keep getting this message: Missing Dependency: libossp-uuid.so.15 is needed by package postgresql-contrib I ran yum update postgresql separately and now it's 8.3.8.

• Is MySQL better than PostgreSQL in something?

  - by Massimiliano Torromeo

  I know the question sounds provocative but it really isn't. I'm lately finding MySQL limiting in a lot of areas and liking PostgreSQL more and more. It scales a lot better and it respects the SQL standards a lot more than MySQL. I'm still a newbie in the PostgreSQL world though and since I'm willing to move away from MySQL for all my future projects, what I want to know is: is there any particular feature of MySQL that it is done better (as in more performant or more user friendly etc..) than in PostgreSQL? I'm wondering what I'm gonna miss from MySQL. I already found that the AUTO_INCREMENT fields in MySQL are more handy than SEQUENCES in PostgreSQL and the deployment in windows was problematic in the past (not a problem anymore. never a problem for me). What else? Thanks.

• PostgreSQL has no service name on CentOS

  - by Kyle MacFarlane

  I installed PostgreSQL in a pretty standard way on CentOS 5.5: rpm -ivh http://yum.pgrpms.org/reporpms/9.0/pgdg-centos-9.0-2.noarch.rpm yum install postgresql90-server postgresql90-contrib chkconfig postgresql-90 on /etc/init.d/postgresql-90 initdb But for some reason I can't use it with the service command because it has no name, .e.g if I do service --status-all I get back the following: master (pid 3095) is running... (pid 3009) is running... rdisc is stopped Or even just /etc/init.d/postgresql-90 status: (pid 3009) is running... So how can I give it a name so that I don't have to type out the whole init script path each time?

• Any good PostgreSQL client for linux?

  - by senotrusov

  stackoverflow points me "belongs-on-serverfault" on this, so crossposting. I am frustrated of not having a good Linux GUI administration and development tool for PostgreSQL. pgAdmin III is buggy and unusable piece of... hmm, software, compared to Windows-only PostgreSQL Maestro and EMS PostgreSQL manager. phpPgaAmin does not looks promising. EMS PostgreSQL manager can work under Wine, but such setup have a number of issues. Requirements are: Table data editing and browsing for large tables (1M+), able to jump by FK or some master-slave editing, GUI filtering and so on. ER diagrams with in-place schema editing Schema editing and browsing with all useful GUI support Schema changes log to put into DB versioning (migrations script). Tabbed interface to be able to work with a number of tables and SQL queries at once. And so on. Any ideas?

• Cannot change PostgreSQL port

  - by Jerec TheSith

  I run Postgresql 8.4 as a service on a CentOS 6.2 server. I set port = 21444 and listen_addresses = '*' in /var/lib/pgsql/data/postgresql.conf and I changed 5432 to 21444 in postmaster.opts and restarted postgres, but when I run netstat -lntp postgresql is still running on port 5432 tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 20276/postmaster When I restart postgresql I get a writting error warning on /proc/self/oom_adj, but the service starts anyway. I read that we could get this error when using virtualized servers, but I don't really know if this has inpact on postgresql listening port. The correct pgsql config file is loaded in /var/lib/pgsql/data : [root@srv02 ~]# ps -ef | grep postgres root 1358 22140 0 09:42 pts/0 00:00:00 grep postgres postgres 9519 1 0 Mar16 ? 00:00:01 /usr/bin/postmaster -p 5432 -D /var/lib/pgsql/data postgres 9573 9519 0 Mar16 ? 00:00:00 postgres: logger process postgres 9575 9519 0 Mar16 ? 00:00:05 postgres: writer process postgres 9576 9519 0 Mar16 ? 00:00:03 postgres: wal writer process postgres 9577 9519 0 Mar16 ? 00:00:01 postgres: autovacuum launcher process postgres 9578 9519 0 Mar16 ? 00:00:01 postgres: stats collector process any thought ? thanks, Jerec

• Complete solution to upgrade PostgreSQL on debian production server

  - by Daimon

  I'm using Debian 6 (Squeeze) in production for a couple of websites. I decided to use postgresql backports so that I could use PostgreSQL 9.0 features. I thought that it would remain 9.0 and receive updates to that major version. Unfortunetly Squueze backports were updated to PostgreSQL 9.1 so probably I won't receive updates to 9.0. I'm planning upgrading to 9.1 but I know that it's not done automatically. I've read about official pg_upgrade and debian's pg_upgradecluster, but I would appreciate complete guide to upgrade. What are steps to do (first apt-get install postgresql, then pg_upgradecluster, then remove old cluster)? List of steps would be nice. What are possible failure scenarios? How to prepare to failures and react on them? I can stop database for a couple of hours only so I want to be prepared

• How to thoroughly purge and reinstall postgresql on ubuntu?

  Somehow I've managed to completely bugger the install of postgresql on Ubuntu karmic.

After I've done: apt-get purge postgresql apt-get install postgresql It said Setting up postgresql-8.4 (8.4.3-0ubuntu9.10.1) ...

Please create it manually with pg_createcluster 8.4 main --start or a similar command (see 'man pg_createcluster'). update-alternatives: using /usr/share/postgresql/8.4/man/man1/postmaster.1.gz to provide /usr/share/man/man1/postmaster.1.gz (postmaster.1.gz) in auto mode. Setting up postgresql (8.4.3-0ubuntu9.10.1) ... I have a "/etc/postgresql" with nothing in it and "/etc/postgresql-common/" has a 'pg_upgradecluser.d' directory and root.crt and user_clusters files. The /etc/passwd has a postgres user; the purge script doesn't appear to touch it. There's been a bunch of symptoms which I work through only to expose the next. Right this second, when I run that command "pg_createcluster..." it complains that '/var/lib/postgresql/8.4/main/postgresql.conf does not exist', so I'll go find one of those but I'm sure that won't be the end of it. Is there not some easy one-liner (or two) which will burn it completely and let me start over?

• Install postgresql. Why is initdb unavailable?

  - by Starkers

  I'm following these instructions, however I can only get to step 17.2. Despite installing postgresql successfully via the sudo apt-get install postgresql command, upon running initdb -D /usr/local/pgsql/data Ubuntu tells me that it 'initdb' isn't installed. The instructions tell me this command is installed by sudo apt-get install postgresql so what's going on? I can make initdb available by installing postgres-xc, but I think postgres-xc is just some weird third party rubbish, and it's not detailed in the instructions. Any ideas?

  I have problem with starting PostgreSQL 8.4 on Ubuntu 9.10 Server after blackout. When I try to connect to the database it says: psql: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.

• PostgreSQL / Ruby for commercial application

  - by RPK

  I am planning a web-based commercial application with front-end RoR and back-end PostgreSQL. I've some confusion about RoR and PostgreSQL Edition to use. For RoR, I have Aptana RADRails installed. For PostgreSQL, a free variant is also available at EnterpriseDB. Previously I installed a free EnterpriseDB PostgreSQL variant and it was very smooth and had professional touch. It was quite different from the one available from PostgreSQL website. I want to know which IDE and RoR variant to use for my project. I have no idea of Ruby and Rails. I will be learning and developing simultaneously. Also, which PostgreSQL variant to use? Can these two technologies be used for a developing a commercial application?

• Pgagent startup script (under the postgres user)

  - by Dominique Guardiola

  Hello, I'm trying to make a clean startup script for pgagent I found one here but I don't see how I can change this : if start-stop-daemon --start --quiet --pidfile /var/run/pgagent.pid \ --exec /usr/bin/pgagent "hostaddr=127.0.0.1 dbname=postgres user=postgres \ password=XXXXXXX";then to launch something like this : su - postgres -c /usr/bin/pgagent "hostaddr=127.0.0.1 dbname=postgres user=postgres" in order to avoid to hard-code the PG password in the script. This is possible using the .pgpass file feature. It works when I'm logged under the postgres user. So my only problem left is how to launch this command under the postgres user tried to add --user=postgres in the call, like mentioned here but it does not work.

• Completely remove Postgres on Mac OSX Lion

  - by Nai

  I'm trying to get postgis running on my machine. Running brew install postgis seems to have installed postgres 9.2.1 on to my machine. I would like to remove my previous version 9.1.2 to keep my environment clean. Running brew uninstall postgres removes 9.2.1. What's the best way to do this? UPDATE nai@nyc ~ $ brew versions postgresql 9.2.1 git checkout ed92469 /usr/local/Library/Formula/postgresql.rb 9.2.0 git checkout 2f6cbc6 /usr/local/Library/Formula/postgresql.rb 9.1.5 git checkout 6b8d25f /usr/local/Library/Formula/postgresql.rb 9.1.4 git checkout c40c7bf /usr/local/Library/Formula/postgresql.rb 9.1.3 git checkout 05c7954 /usr/local/Library/Formula/postgresql.rb 9.1.2 git checkout dfcc838 /usr/local/Library/Formula/postgresql.rb 9.1.1 git checkout 4ef8fb0 /usr/local/Library/Formula/postgresql.rb 9.0.4 git checkout 2accac4 /usr/local/Library/Formula/postgresql.rb 9.0.3 git checkout b782d9d /usr/local/Library/Formula/postgresql.rb 9.0.2 git checkout 2c3b88a /usr/local/Library/Formula/postgresql.rb 9.0.1 git checkout b7fab6c /usr/local/Library/Formula/postgresql.rb 9.0.0 git checkout 1168d8f /usr/local/Library/Formula/postgresql.rb 8.4.4 git checkout c32bea0 /usr/local/Library/Formula/postgresql.rb 8.4.3 git checkout 237d1c5 /usr/local/Library/Formula/postgresql.rb

• PostgreSQL timezone does not match system timezone

  - by Martin C.

  I have several PostgreSQL 9.2 installations where the timezone used by PostgreSQL is GMT, despite the entire system being "Europe/Vienna". I double-checked that postgresql.conf does not contain timezone setting, so according to the documentation it should fallback to the system's timezone. However, # su -s /bin/bash postgres -c "psql mydb" mydb=# show timezone; TimeZone ---------- GMT (1 row) mydb=# select now(); now ------------------------------- 2013-11-12 08:14:21.697622+00 (1 row) Any hints, where the GMT timezone could come from? The system user does not have TZ set and the /etc/timezone and /etc/timeinfo seem to be configured correctly. # cat /etc/timezone Europe/Vienna # date Tue Nov 12 09:15:42 CET 2013 Any hints are appreciated, thanks in advance!

• PostgreSQL won't start anymore

  - by Sander Declerck

  Today, my PostgreSQL doesn't start anymore on my windows machine... I've tried to start the service in windows services and got the following error: Windows could not start the PostgreSQL Database Server 8.3 service on Local Computer.

Then I went to the command line to manually start C:/Program Files (x86)/PostgreSQL/8.3/bin/psql.exe, and then I got this error: psql: Could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "???" and accepting TCP/IP connections on port 5432?

• ASP.NET, PostgreSQL, Mono, Ubuntu, Apache: Good idea?

  - by wreck_of_u

  I am a long-time Microsoft .NET developer. ASP.NET/MSSQL/IIS has been my bread & butter over the past 6 years. Now, I'm getting fond of the "lightweightness" of Ubuntu 10.xx server. I'm also loving SSH-ing it from my Windows 7 PC and installing apps using the awesome "apt-get" command. I've also been using HeidiSQL with MySQL now and loving it. It feels like Management Studio. However, i've read that PostgreSQL "may" be better than MySQL, and I did experience some MySQL overloads in my Moodle box (but this can be just a poor tweaking in my part). My question is, would it be a good idea to run this configuration? ASP.NET 4.0 PostgreSQL (the latest one I can apt-get!) Ubuntu 10.10 with Mono running on Apache Also, I assume I would be using Npgsql for Mono as my connector from ASP.NET to PostgreSQL?

• VirtualBox Port Fowarding to Connect to PostgreSQL Database

  - by kliao

  I'm trying to connect to a PostgreSQL database hosted on a Win7 guest from a Win7 host. I've configured security in pg_hba.conf host all all 127.0.0.1/32 md5 host all all 10.0.2.15/32 md5 host all all 192.168.1.6/32 md5 and set the listen_addresses setting in postgresql.conf to '*'. I think I've set up port forwarding correctly as I see: Key: VBoxInternal/Devices/e1000/0/LUN#0/Config/win7_vm1/GuestPort, Value: 5432 Key: VBoxInternal/Devices/e1000/0/LUN#0/Config/win7_vm1/HostPort, Value: 5432 Key: VBoxInternal/Devices/e1000/0/LUN#0/Config/win7_vm1/Protocol, Value: TCP when I call getextradata. This is similar to http://serverfault.com/questions/106168/cant-connect-to-postgresql-on-virtualbox-guest but I'm not sure what I'm doing wrong. In the vbox.log file I see: 00:00:01.019 NAT: set redirect TCP host port 5432 = guest port 5432 @ 10.0.2.15 00:00:01.033 NAT: failed to redirect TCP 5432 = 5432 but I'm not sure how to fix that. Any ideas? Thanks.

• How to migrate data from a Firebird database to PostGreSQL on Linux

  - by Tom Feiner

  Are there any good tools to migrate existing firebird databases to PostgreSQL for Linux systems? I've looked at: FBexport which can be used to dump the data as insert statements, but it's mainly written to export/import from one firebird db to another, not as a migration tool. There's also: Firebird to PostgreSQL Win32 tool, but it's only for win32 systems. Is there any good tool to do this? Or should I just roll my own?
