Thread: udp port

Just out of curiosity: What does postmaster need the UDP port for? (Is
it documented somewhere? I cannot find anything in the documentation).

PostgreSQL-7.2b2

Relevant output from netstat -p -a:

Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
PID/Program name
tcp        0      0 *:ssh                   *:*                     LISTEN

That would be the connection to the statistics collector subprocess.
See discussions in pghackers from about six or eight months ago.
