logging connections - Mailing list pgsql-general

i want to know, how i can log connections to postgres.

the sample log file is:
LOG:  shutting down
LOG:  database system is shut down
LOG:  database system was shut down at 2006-01-17 18:18:24 CST
LOG:  checkpoint record is at 0/B035D0
LOG:  redo record is at 0/B035D0; undo record is at 0/0; shutdown TRUE
LOG:  next transaction ID: 1267; next OID: 17728
LOG:  database system is ready
LOG:  unexpected EOF on client connection
LOG:  unexpected EOF on client connection
LOG:  unexpected EOF on client connection
LOG:  received fast shutdown request
LOG:  aborting any active transactions
FATAL:  terminating connection due to administrator command
LOG:  shutting down
LOG:  database system is shut down
LOG:  database system was shut down at 2006-01-20 11:00:00 CST
LOG:  checkpoint record is at 0/3C339CB4
LOG:  redo record is at 0/3C339CB4; undo record is at 0/0; shutdown TRUE
LOG:  next transaction ID: 2283381; next OID: 1159413
LOG:  database system is ready
LOG:  unexpected EOF on client connection
LOG:  unexpected EOF on client connection
LOG:  unexpected EOF on client connection
LOG:  unexpected EOF on client connection
LOG:  unexpected EOF on client connection



however, i am still not able to know how to log into the above file,
who has connected etc


if i can log something like " LOG:  connection received: host=client1
> port=3775"

and also if i shut down postmaster, using pg_ctl stop, no logging takes place to the above log file.

How to enable the above,

thanks,
regards
Surabhi

It tries to connect, gets told it needs a password (the log verbosity
level is not high enough to record the rejection), asks you for the
password, and connects again.  I don't see anything funny here.
