psql databases owned by 'admin' -

[BrendanH]

A customer signed up with us specifically because we offer postgres. He was under the impression that the database would be owned by his user and not by 'admin' as it is now. I don't consider this to be a bug but I'm also very hesitant to "manually" set his user to be the owner.

What are the repercussions for changing the owner and what is the specific reason that Plesk sets admin to be the owner?
Is there a way to have the databases automatically owned by the db user?
