Обсуждение: function "XXX" already exists with same argument types
Hello,
I use PostgreSQL 8.4 under CentOS 5.7:
# rpm -qa | grep post
compat-postgresql-libs-4-1PGDG.rhel5
postgresql-8.4.9-1PGDG.rhel5
postgresql-server-8.4.9-1PGDG.rhel5
compat-postgresql-libs-4-1PGDG.rhel5
postgresql-libs-8.4.9-1PGDG.rhel5
postgresql-devel-8.4.9-1PGDG.rhel5
And perform nightly backups with this cronjob:
1 1 * * * pg_dump $PGDATABASE | gzip -c >
$HOME/backups/pref-`date +\%F`.sql.gz
I also restored them on the same and another
machines (dev. VMs) often and w/o problems.
Now I'm trying to migrate to another machine
and CentOS 6 and suddenly emits the warnings:
# rpm -qa|grep post
postgresql-libs-8.4.7-2.el6.x86_64
postgresql-devel-8.4.7-2.el6.x86_64

The 1st waring is ok, as I've run "create language plpgsql" before.
But why do I get the function warings?
In my original database I don't see any duplicates with \df or \df+
# psql
psql (8.4.9)
Type "help" for help.
pref=> \df pref_update_catch

Same picture in my target database on CentOS 6.0
(it has 8.4.7 and not 8.4.9 though)
Any ideas what is happening please?

Likely someone mistakenly added the functions to template1 of the machine you're restoring onto and they're getting addedto the new database when it's created. Michael Glaesemann grzm seespotcode net
Thank you Michael, but no -

It does not run in a transaction, unless you ask it to, so if it failed on something and you want torun it again, you should drop the database and create it again.<br /><br />

What is you drop and recreate the database, then run \dfS in a superuser psql session to make sure there is nothing there, then restore. Yours, Laurenz Albe
Thanks for your comments, the problem has disappeared on the 2nd restore, but I'll keep you suggestions in mind!
