Dave,
Another aspect of this problem is that, on most platforms, the children
of postmaster that are forked for each connection rename themselves
to 'postgres'. The code for this was changed, recently, due to some
potential speed, security, or portability problems (I'm not sure off
the top of my head). You may be on a platform that no longer renames,
so you'll end up with multiple processes names 'postmaster', and have
to track down which is which they way Peter pointed out.
