Hello,

I have a Bacula script that does an automatic backup of a Postgres Database. The script makes two backups using (pg_dump) of the data base :

The schema only and the data only.

/usr/bin/pg_dump --format=c -s $dbname --file=$DUMPDIR/$dbname.schema.dump
/usr/bin/pg_dump --format=c -a $dbname --file=$DUMPDIR/$dbname.data.dump

The problem is that I can't figure out how to restore it with pg_restore.

Do I need to create the database and the users before then restore the schema and finally the data.

I did the following :

pg_restore  --format=c -s -C -d template1 xxx.schema.dump
pg_restore  --format=c -a -d xxx xxx.data.dump

This first restore creates the database with emtpy tables but the second gives many error like this one :

pg_restore: [archiver (db)] COPY failed: ERROR:  insert or update on table "Table1" violates foreign key constraint "fkf6977a478dd41734"
DETAIL:  Key (contentid)=(1474566) is not present in table "Table23".

Any ideas?
