Just when I am ready to throw it away, I come up with a use for the
function:
test=> select * from pg_stat_activity where procpid != backend_pid();
This shows all activity _except_ my session, which pgmonitor or others
may want to use, and I can think of no other way to do it.
Comments? Maybe this is why it should be called pg_backend_id and put
in the stat section.
