Default Ubuntu post-install Qs (PG v7.4)

1) Am I right when I assume an init.d type of start/kill scenario is
used?

2) The ps -ef shows the process:
/usr/lib/postgresql/7.4/postmaster -D /var/lib/postgresql/7.4/main
postgres: stats buffer process
postgres: stats collector process
I see no logfile explicitly defined. Where is that specified?

3) In /var/log/postgresql I am getting logging, but not enough. How
can I get more details?

4) User postgres keeps getting the following showing up:
postgres(at)smithrn-ltb2:/tmp$ 2007-10-08 20:02:01 LOG: incomplete
startup packet
2007-10-08 20:07:29 LOG: recycled transaction log file
"000000010000007D"
2007-10-09 00:02:02 LOG: incomplete startup packet
2007-10-09 05:02:01 LOG: incomplete startup packet
2007-10-09 10:02:01 LOG: incomplete startup packet

Thank you!
