Обсуждение: cleaning up template1

I remember when I first play with postgresql, I play with template1
directly not created first the database ( then play with it ). So I just
want to know is there any way to cleaning up the template1?

Regards,

Akbar

You can look for non-system objects stored in template1 and delete them,
or you can use pg_dump and it will show the changes made to template1 in
the dump.

This should do the trick.

xinu=# update pg_database set datistemplate = false where datname ='template1';
UPDATE 1
xinu=# drop database template1;
DROP DATABASE
xinu=# create database template1 with template = template0;
CREATE DATABASE
xinu=# update pg_database set datistemplate = true where datname ='template1';
UPDATE 1
