Re: pg_restore error

I finally got a chance to try out your suggestions, but it seems that
something I'm doing is still wrong.

When I try the first method described below, I get this error:

You are now connected as new user postgres.
ERROR: function plpgsql_call_handler already exists with same argument
types
ERROR: Language plpgsql already exists
\connect: FATAL 1: IDENT authentication failed for user "cmortensen"

When I try the other method, I get this error:

pg_restore: [archiver (db)] could not execute query: ERROR: function
plpgsql_call_handler already exists with same argument types

I get the impression that the problem is deeper than just trying to backup,
but being a very green novice to Postgres, I'm not sure where to start
tracking the problem to its source...

Thanks for all your help so far :)

Hi Curtis,

> thanks for the advice. i now have a different error. :(

I suspected you would, but without knowing the commands you were using
decided guessing would only be confusing! Only the archive formats
from pg_dump are intended to be used with pg_restore. The default
output can be restored by psql:

$ pg_dump fubar > fubar.sql
$ createdb fubar2
CREATE DATABASE
$ psql fubar2 < fubar.sql
You are now connected as new user giles.
CREATE
$

$ pg_dump --format=c fubar > fubar.dump
$ createdb fubar2
CREATE DATABASE
$ pg_restore --dbname=fubar2 < fubar.dump
pg_restore: [archiver] WARNING:
Data restoration may fail because existing triggers cannot be disabled
(no superuser user name specified). This is only a problem when
restoring into a database with already existing triggers.
