Обсуждение: Perhaps silly question about empty search_path

Hello;

To begin with, I'm not certain how useful it would be... that said; it
seems odd that a role or DB can have it's config search_path set to
empty string but you can't explicitly set it that way.

One possible use for this might be to force complete schema
qualification when developing  DB update scripts.

Comments?

Ugh!

Sorry.  I forgot to see if set_config('search_path', '', true/false) does
the trick and it does.

Well, anyway... I got stuck on it since accomplishing what I had
intended wasn't straight forward :-)

Thanks
