I've used PostgreSQL on lots of Unixes.  Most of the advantages and
disadvantages of those are not database-specific.  Here are some
pro's of each of them:

BSDs:  centralized, well-organized code management, code well thought-out
and readable, especially NetBSD.  Good performance and reliability.

Linux:  supports hardware faster, so if you want to play video games
or have rare network cards, use this.

Mac OS:  pleasing user interface, easier administration for
non-technicians, good performance

Solaris:  superior OS architecture and features, esp. in Solaris 10
(unbeatable diagnostics with dtrace/mdb), high degree of automization
(hands-off installation and configuration of everything)

Notice:  BSD, Linux, and Solaris cost nothing.  Mac OS is payware.
Sources are available for BSDs, Linux, Mac OS (the "Unix" subset),
and (within the next 5 weeks) Solaris.

So, if you're a professional, go with NetBSD or Solaris.
If you want a system that your grandparents (may they still be living)
feel comfortable with, take Mac OS X.
