Turning on logging

[Owen Hartnett <owen@xxxxxxxxxxxxxxxx>]

I know this is in the docs somewhere, and it's probably staring me in 
the face, but I haven't been able to find it:

I'm running 8.2.4 through npgsql - how do I log:

1) connections to the database

2) updates, deletes, adds


Is this set in the ./configuration?  Or in the startup command line? 
I'm running on Mac OS X server using the Ray Aspeitia/David Wheeler 
startup script with log rotation turned on (using 
/usr/sbin/rotatelogs the Apache log rotation utility).

Thanks for the help!
