Hi,
Is there a reliable way to determine how many (if any) users are
currently using any given database (or whether or not postgres is currently
in use) -- short of bringing down the postmaster and restarting it?
Thanks,
Brendan

You can get the needed info using ps (or top)
The following is in linux (on other systens the flags to ps may differ):
[hannu@kodu hannu]$ ps ax | grep postgres
604 p1 S 0:00 grep postgres
600 ? S 0:00 /usr/bin/postgres localhost hannu unidocu idle
the 8th field is db name, so you can probably write a short script
(sh, awk, python, perl, ...) to do the counting.
the fields >8 is current command, so yo can check what your backends are
doing.
