ERROR: must be owner of extension plpgsql

Today while moving Django/PostgreSQL site between servers and importing an SQL dump into the new location I got a surprising error "ERROR: must be owner of extension plpgsql". I'm already used to PostgreSQL quirks so after a quick search I came to the following solution: Login as postgres user and do:

  1. psql template1


  1. alter role your_role_name with superuser;

That will make your current user as superuser and give him permissions to own plpgsql language.
