...and that all meant what? The postgres manual is open to much
interpretation to anyone new trying to understand its contents. Combine
that with documentation that's still not written, or broken across several
different sections (programmer, user, admin, etc) and a search engine which
returns absolute crap.... well I guess us new users can just go use MySQL.
as far as I can tell the above sounds like a complicated work-around to a
bug, but maybe you'll be kind enough to correct me on this...?
