I can vouch for this also.  We have a (lightly loaded) zope server
that handles bug tracking with a PostgreSQL database.  As far as I can
tell it will run forever, at least it has never failed in the year and
a half we've had it up. The only thing keeping us from 3-figure
uptimes (100s of days) is the power.  I guess we should buy a ups, eh?

The major thing you need to watch for is memory leaks.  Run the thing
with load for a while and watch the thing with top or ps or something
to make sure the memory usage doesn't grow.
