PostgreSQL 9.1 pg_restore error regarding PLPGSQL

Question

I am using Postgres for a django project and I am currently implementing a database backup/restore system that as simple as possible performs a pg_dump when the user clicks

Answer 1

I found the following workaround on this page:

http://archives.postgresql.org/pgsql-general/2011-10/msg00826.php

The idea is to use pg_restore -l to list the contents of the archive, grep out the extension that the user doesn't have permission to restore, and use pg_restore -L to use this elided list when restoring.

For example:

pg_restore -l ~/database.dump | grep -v "EXTENSION - plpgsql" > ~/restore_elements
pg_restore -L ~/restore_elements ~/database.dump
