What did you move from? The Solaris ps (not in ucb, which is the
BSD-style ps) shows the parent process name, so everything shows up
as "postmaster" rather than "postgres". There's always one back end
per connection.
If you are in fact using more connections, by the way, I can tell you
that Solaris 8, in my experience, is _very bad_ at managing context
switches. So you may not be merely I/O bound (although your other
reports seem to indicate that you are).
