Обсуждение: createdb problem

I use postgresql 7.4.8.
I need te delete and recreate a database very ofent, because I do some
tests in it.
After a few months the command createdb becamed very slow.

How can I make it go fast again?
Thank you.

The only explanation that comes to mind is that you haven't ever
vacuumed pg_database ... at this point you probably need a VACUUM
FULL, and maybe REINDEX too, to get it back down to a reasonable
size.

My guess is you need to vacuum. Try a vacuumdb -a.
