Обсуждение: dropping template1
I'm using 7.3 and accidently created unnecessary functions and such in template1. Originally it had nothing added beyond the initial install (initdb). I would like to return it to the clean state. drop database template1; ERROR: DROP DATABASE: database is marked as a template Is there another way?

If you absolutely instist, shutdown postmaster, go to database dir, do a rm -rf there and doa initdb once again. Clean as slate..

Clean as slate.. My initial concerns about the above advice where related to users and groups and the potential for loss of that data. After reading http://www.us.postgresql.org/users-lounge/docs/7.2/postgres/managing-databases.html I'm not as worried, but it got me wondering... Where are the user and group data held?

Of course in the same place. But if you are feeling lazy to drop each function by hand, what is the alternative left? You decide which one is labour intensive? Dropping functions or recreating users.. Bye Shridhar -- Ingrate, n.: A man who bites the hand that feeds him, and then complains of indigestion.

Try this: (1) UPDATE pg_database SET datistemplate = false WHERE datname = 'template1'; (2) DROP DATABASE template1; (3) CREATE DATABASE template1 WITH template template0; (4) UPDATE pg_database SET datistemplate = true WHERE datname = 'template1'; Cheers, Neil -- Neil Conway <neilc@samurai.com> || PGP Key ID: DB3C29FC

Unless you did weird things, all functions and datatypes will be in non-system schema's. Dropping and recreating the schema's will implicitly drop the functions and datatypes as well. Don't forget to vacuum freeze after that. Jochem
