'idle' processes in v6.5?

this might be something new that I didn't see go through, or, at least,
get implemented...but, under a Linux system, fresh install this morning,
of v6.5:

19130 p2 S 0:00 /usr/local/pgsql/bin/postmaster -o -F -o /usr/local/pgsql/er
19416 p2 S 0:00 /usr/local/pgsql/bin/postgres 127.0.0.1 nobody imp idle
19418 p2 S 0:00 /usr/local/pgsql/bin/postgres 127.0.0.1 nobody imp idle
19425 p2 S 0:00 /usr/local/pgsql/bin/postgres 127.0.0.1 nobody imp idle
21163 p2 S 0:00 /usr/local/pgsql/bin/postgres 127.0.0.1 nobody imp idle
21288 p2 S 0:00 /usr/local/pgsql/bin/postgres 127.0.0.1 nobody imp idle
21290 p2 S 0:00 /usr/local/pgsql/bin/postgres 127.0.0.1 nobody imp idle
21303 p2 S 0:00 /usr/local/pgsql/bin/postgres 127.0.0.1 nobody imp idle
21445 p2 S 0:00 /usr/local/pgsql/bin/postgres 127.0.0.1 nobody imp idle

yet nobody is using that system yet except me testing a couple of times...

^^^^^

Ah, finally seen the light...
You didn't expect _that_ to go unnoticed, did you?

Yes, "nobody" *is* using the system. You sure you don't have a web
server or something? Anything else running as "nobody"?

I'm getting paid *well* to put up with it :)

Ya, but no connections through it yet...does PHP auto-open connections to
the backend as a sort of cache/pool?

Well, that story will work for a while...

afaik, yes. Haven't run it myself though. I imagine that there are
tunable parameters for that sort of thing.

No, no auto-open connections. From the database name (imp), I
would guess that you are running the IMAP web frontend named IMP
which is using persistent connections to the database - these
aren't closed automatically, so they hang around idle.
