8.1 display in top

["Chris Hoover" <revoohc@xxxxxxxxx>]

Quick question.

I am looking at top on my RH AS 4.0 server that runs my PG 8.1
database.  When I see a db process in top, it says postgres: user
db ipaddr(number) condition (i.e. postgres: user1 db1 10.4.10.10(23456)
SELECT).

What does the number after the ip address represent (the (23456)]?

Thanks,

Chris
