  • How to specify "PG-USERNAME" in pg_ident.conf so that it'll match any database user ?

    - by felace
    I need to restrict a specific unix user so that it can login with only a few select postgres usernames (with password prompt), but allowing every other user to use whatever pg username they want. Assuming restrUnixUser is the unix user name and restrUser is one of the postgres users it may use, and AllowedDB is the only database they should connect to : pg_hba.conf : local AllowedDB restrUser password local all restrUser reject local all all ident map=exceptrestrUser And pg_ident.conf : exceptrestrUser /^(?!restrUnixUser).*$ user1 exceptrestrUser /^(?!restrUnixUser).*$ user2 exceptrestrUser /^(?!restrUnixUser).*$ postgres does what I exactly want to do right now, however, I'll probably add a lot more users so I wonder if there is something like mapname unixuserpattern allpgusers that'll match with whatever username used to login by any unix user matching the pattern.

  • count number of rows to be affected before update in trigger

    - by tomaszsobczak
    Hi, I want to know number of rows that will be affected by UPDATE query in BEFORE per statement trigger . Is that possible? The problem is that i want to allow only queries that will update up to 4 rows. If affected rows count is 5 or more i want to raise error. I don't want to do this in code because i need this check on db level. Is this at all possible? Thanks in advance for any clues on that

  • Why is one query consistently ~25ms faster than another in postgres?

    - by Emory
    A friend wrote a query with the following condition: AND ( SELECT count(1) FROM users_alerts_status uas WHERE uas.alert_id = context_alert.alert_id AND uas.user_id = 18309 AND uas.status = 'read' ) = 0 Seeing this, I suggested we change it to: AND NOT EXISTS ( SELECT 1 FROM users_alerts_status uas WHERE uas.alert_id = context_alert.alert_id AND uas.user_id = 18309 AND uas.status = 'read' ) But in testing, the first version of the query is consistently between 20 and 30ms faster (we tested after restarting the server). Conceptually, what am I missing?

  • Looking to get a small server – need web, PHP, PostgreSQL.

    - by Javawag
    Hi all! I'm looking to get a cheap (low end) server to serve web pages (xHTML/PHP), but I also need to be able to set up PostGreSQL on the system too. Ideally the server would have low power consumption, run Linux (I prefer Mac OS X but a Mac Mini, although the size I'm looking for, is too much money!) and be around £100 (~$160US). EDIT: Just to make it clearer, I'm looking to purchase the server hardware myself – but I want something about Mac Mini sized. I don't want to pay for hosting! Also, quick question – if it's to serve web pages from my home (standard ISP connection, no static IP!), what do I need in place to get this working. I'm guessing I would sign up with some service like no-ip, and register a domain to point to my no-ip address (then install the no-ip software on the server to update that with the current IP). I know the idea of running a server behind a normal ISP connection isn't very elegant, but I'd prefer to have the server where I can see it then pay over the odds for a hosting service where I have little to no control over what happens. Also, I could write my own server software for apps/etc to connect to as well. Anyways I'm rambling! What do you guys think?! Javawag

  • How secure is a PostgreSQL database if my server is stolen?

    - by orokusaki
    If I have a server with a database if top secret data in PostgreSQL and my password is practically impossible to crack (128 character string of all sorts of weird chars, generated by hand). The server password is also uncrackable in theory (basically, ignore the possibility of a password crack on the DB). Aside from a password crack, how easy is it to get the data out of this database? Assumptions: Only the DB exists on the server. There is no password in a PHP script or anything like that The person who has the server is a computer / DB / hard-drive recovery expert I'm not using any hard-drive encryption or anything out of the norm for protection I'm trying to understand the risks involved with somebody gaining physical access to my server's hard-drives.

  • Which is better for multi-use auth, MySQL, PostgreSQL, or LDAP?

    - by Fearless
    I want to set up an Oracle Linux 6 server that gives users secure IMAP email (with dovecot), Jabber IM, FTP (with vsftpd), and calDav. However, I want each user logon to be able to authenticate all services (e.g. Joe Smith signs up once for a username and password that he can use for email, ftp, and his calendar). My question is, which database service will be best suited for that application? Also, is there a way to link the database with the preexisting server shell logins (e.g. so I can read the root account's LogCheck emails on a different device)?

  • Installation of gearmand fails on libevent dependency

    - by PeeHaa
    I've installed the PostgreSQL yum repo and have PostgreSQL running for some time now, but now when I try to install gearmand I get the following errors: Transaction Check Error: file /usr/bin/event_rpcgen.py from install of compat-libevent14-1.4.13-1.rhel6.x86_64 conflicts with file from package libevent-devel-2.0.12-1.rhel6.x86_64 file /usr/lib64/libevent_core.a from install of compat-libevent14-1.4.13-1.rhel6.x86_64 conflicts with file from package libevent-devel-2.0.12-1.rhel6.x86_64 file /usr/lib64/libevent_core.so from install of compat-libevent14-1.4.13-1.rhel6.x86_64 conflicts with file from package libevent-devel-2.0.12-1.rhel6.x86_64 file /usr/lib64/libevent_extra.a from install of compat-libevent14-1.4.13-1.rhel6.x86_64 conflicts with file from package libevent-devel-2.0.12-1.rhel6.x86_64 file /usr/lib64/libevent_extra.so from install of compat-libevent14-1.4.13-1.rhel6.x86_64 conflicts with file from package libevent-devel-2.0.12-1.rhel6.x86_64 This is because the libevent is coming from the postgresql repository, so I thought I just disable the postgresql repository and try again: yum --disablerepo=pgdg91 install gearmand Error: Package: gearmand-0.14-3.el6.2.x86_64 (epel) Requires: libevent-1.4.so.2()(64bit) Available: libevent-1.4.13-1.el6.x86_64 (base) libevent-1.4.so.2()(64bit) Installed: libevent-2.0.12-1.rhel6.x86_64 (@pgdg91) Not found Is there a way to keep the libevent version used by postgresql and at the same time install gearmand (with the correct libevent version)?

  • How to install pgAdmin

    - by Kifsif
    I use Ubuntu 12.04 64 bit. At first I installed pgAdmin through Software Center. But it seemed old. So, I decided to uninstal it. Then I downloaded graphic installer for PostgresQL. sudo ./postgresql-9.2.1-1-linux-x64.run I was warned that a previous version of pgAdmin is found, it will be upgraded but I'll have to restart the server. Well, installation process worked. Then I turned out in terminal again. I restarted the server /etc/init.d$ sudo ./postgresql-9.2 restart /opt/PostgreSQL/9.2/pgAdmin3/bin$ ./pgadmin3 The answer is: The program 'pgadmin3' is currently not installed. So, I can't find my pgAdmin to launch it. Could you suggest me anything?

  • New database profiling support in ANTS Performance Profiler

    - by Ben Emmett
    In May last year, the ANTS Performance Profiler team added the ability to profile database requests your application makes to SQL Server or Oracle. The really cool thing is that you’re shown those requests in the application’s call tree, so you can see what .NET code caused those queries to run. It’s particularly helpful if you’re using an ORM which automagically generates and runs queries for you, but which doesn’t necessarily do it in the most efficient way possible. Now by popular demand, we’ve added support for profiling MySQL (or MariaDB) and PostgreSQL, so you can see queries run against those databases too. Some of you have also said that you’re using the Devart dotConnect data providers instead of the native .NET ones, so we’ve added support for those drivers too. Hope it helps! For the record, here’s a list of supported connectors (ones in bold are new): SQL Server .NET Framework Data Provider Devart dotConnect for SQL Server Oracle .NET Framework Data Provider Oracle Data Provider for .NET Devart dotConnect for Oracle MySQL / MariaDB MySQL Connector/Net Devart dotConnect for MySQL PostgreSQL Npgsql .NET Data Provider for PostgreSQL Devart dotConnect for PostgreSQL SQL Server Compact Edition .NET Framework Data Provider for SQL Server Compact Edition Devart dotConnect for SQL Server Pro Have we missed a connector or database which you’d find useful? Tell us about it in the comments or by emailing [email protected]. Ben

  • Why are the packages found with apt-get always horribly out of date?

    - by Andrew
    Whenever I use the package manager, it can only ever find really old versions of stuff. Example: sudo apt-get update sudo apt-get install postgresql The best it can do is version 8.4 (3 years out of date). Trying to get a later version, I get: $ sudo apt-get install postgresql-9.1 Reading package lists... Done Building dependency tree Reading state information... Done E: Couldn't find package postgresql-9.1 I experience the same issue whenever I use the package manager, so I usually just download and build things from source. How can I make it find up-to-date software?

  • Locate a user's bashrc file

    - by Starkers
    Really confused. Upon running cat etc/passwd I have found this: postgres:x:117:126:PostgreSQL administrator,,,:/var/lib/postgresql:/bin/bash meaning I have a postgres user, right? I want to change the bashrc environment file of this user to make commands available to it. /var/lib/postgresql doesn't contain a bashrc file, and /bin/bash doesn't contain it either, so I don't really know what's going on. All I know is a created postgres using the useradd command, so why do I have some weird user with no home directory? So confused :(

  • Should I trust Redis for data integrity?

    - by Jiaji
    In my current project, I have PostgreSQL as my master DB, and Redis as kind of a slave, e.g., when some user adds another as a friend, first the relationship will be stored in PostgreSQL and then a friend list in Redis will be updated. When some user's friend list is requested, it will be pulled out of Redis instead of PostgreSQL. The question is: when I update the friend list in Redis, should I get a fresh copy outof PostgreSQL, and replace the old list in Redis with the new one or should I keep the old list and simply SADD the userid into the list? The latter is of course best for performance, but intuitively the former does a better job in keep the data integrity? And if something like Celery is used, is the second method worth the risk?

  • Optimising speeds in HDF5 using Pytables

    - by Sree Aurovindh
    The problem is with respect to the writing speed of the computer (10 * 32 bit machine) and the postgresql query performance.I will explain the scenario in detail. I have data about 80 Gb (along with approprite database indexes in place). I am trying to read it from Postgresql database and writing it into HDF5 using Pytables.I have 1 table and 5 variable arrays in one hdf5 file.The implementation of Hdf5 is not multithreaded or enabled for symmetric multi processing.I have rented about 10 computers for a day and trying to write them inorder to speed up my data handling. As for as the postgresql table is concerned the overall record size is 140 million and I have 5 primary- foreign key referring tables.I am not using joins as it is not scalable So for a single lookup i do 6 lookup without joins and write them into hdf5 format. For each lookup i do 6 inserts into each of the table and its corresponding arrays. The queries are really simple select * from x.train where tr_id=1 (primary key & indexed) select q_t from x.qt where q_id=2 (non-primary key but indexed) (similarly five queries) Each computer writes two hdf5 files and hence the total count comes around 20 files. Some Calculations and statistics: Total number of records : 14,37,00,000 Total number of records per file : 143700000/20 =71,85,000 The total number of records in each file : 71,85,000 * 5 = 3,59,25,000 Current Postgresql database config : My current Machine : 8GB RAM with i7 2nd generation Processor. I made changes to the following to postgresql configuration file : shared_buffers : 2 GB effective_cache_size : 4 GB Note on current performance: I have run it for about ten hours and the performance is as follows: The total number of records written for each file is about 6,21,000 * 5 = 31,05,000 The bottle neck is that i can only rent it for 10 hours per day (overnight) and if it processes in this speed it will take about 11 days which is too high for my experiments. Please suggest me on how to improve. Questions: 1. Should i use Symmetric multi processing on those desktops(it has 2 cores with about 2 GB of RAM).In that case what is suggested or prefereable? 2. If i change my postgresql configuration file and increase the RAM will it enhance my process. 3. Should i use multi threading.. In that case any links or pointers would be of great help Thanks Sree aurovindh V

  • CentOS 5.5 Package documentation

    - by fthinker
    Usually when I install a common package like PostgreSQL or MySQL or Python etc using Yum it installs the files held within those packages into locations specific to CentOS itself. It may also install scripts specific to CentOS only. These paths may not be the same as the defaults found within the source distributions found on the PostgreSQL, MySQL, Python etc project websites and the scripts are usually unique to CentOS. Recently when I installed PostgreSQL under Ubuntu I found some very nice distribution specific information about how the install was organized and how to use the package in a Ubuntu way. I found this information in /usr/share/doc/ Is there any such information included within CentOS?

  • Faq and Best tips Regarding Learning Database ?

    - by AdityaGameProgrammer
    For a programmer with no prior exposure to databases What would be a good database to learn Oracle vs SQLserver vs MySQLvs PostgreSQL? I have come across lot of discussion MySQL and PostgreSQL and frankly I am confused on which to start with. Are these very different, in the sense if one had to switch, would the exposure to one be counter-productive to learning the other? Is working with databases heavily platform dependent? What exactly do people mean by Data base programming vs. administration? Do people chose databases based on the programming language used for the application developed? In general, Working with databases is it implicit that we work with some server? Does the choice of databases differ when it comes to game development? If so what factors does it differ by? What are the Best Tips that you have found to be useful when learning databases Edit: Some FAQ i had and found the same on SO What should every developer know about databases? Which database if learning from scratch in 2010? For a beginner, is there much difference between MySQL and PostgreSQL What RDBMS should I learn/use? (MySql/SQL Server/Oracle etc.) To what extent should a developer learn database? How are database programmers different from other programmers? what kind of database are used in games?

  • A list of Entity Framework providers for various databases

    - by Robert Koritnik
    Which providers are there and your experience using them I would like to know about all possible native .net Framework Entity Framework providers that are out there as well as their limitations compared to the default Linq2Entities (from MS for MS SQL). If there are more for the same database even better. Tell me and I'll be updating this post with this list. Feel free to add additional providers directly into this post or provide an answer and others (including me) will add it to the list. Entity Framework 1 Microsoft SQL Server Standard/Enterprise/Express Linq 2 Entities - Microsoft SQL Server connector DataDirect ADO.NET Data Providers Microsoft SQL Server CE (Compact Edition) Any provider? MySQL MySQL Connector (since version 6.0) - I've read about issues when using Skip(), Take() and Sort() in the same expression tree - everyone welcome to input their experience/knowledge regarding this. (NOTE: MySQL Connector/NET Visual Studio Integration is not supported in the Express Editions of Visual Studio, meaning you won't be able to view MySQL databases in the Database explorer window or add a MySQL data source via Visual Studio wizard dialog boxes. Some users may find that this limits their ability to use Entity Framework and MySQL within Visual Studio Express). Devart dotConnect for MySQL - similar issues to MySql's connector as I've read and both try to blame MS for it [these issues are supposed to be solved] SQLite Devart dotConnect for SQLite System.Data.SQLite PostgreSQL Devart dotConnect for PostgreSQL Npgsql Oracle Devart dotConnect for Oracle Sample Entity Framework Provider for Oracle - community effort project DataDirect ADO.NET Data Providers DB2 IBM Data Server Provider has EF support.

    I'm creating my first website from hand-coded scratch (just used WordPress and Drupal before) and I'm at the point where I'm setting up my database for the site. However my host has given me 4 options to choose from in the database department. MS SQL Server 2005 MySQL PostgreSQL MySQL 5 Which should I go for? From what I understand PostgreSQL is meant for smaller databases with high access times. Though to be honost I'm not quite sure.
