The following bug has been logged online:

Bug reference: 4591
Logged by: Steblina OLeg
Email address: oldnick(at)ukrlink(dot)net
PostgreSQL version: 8.1
Operating system: Windows XP pro sp2
Description: postgres.exe more than 150 processes runned
Details:

http://apoc.org.ua/oldnick/images/pgsql_processes.jpg

Processes start each other and hang, doing nothing. Connections with base
are not made, for a night 177 processes postgres.exe.

I used version 8.1 instead of newer 8.3 for the reason that the service in
version 8.3 is started and at once stops.

Computer configuration:
Q6600, 2Gb, WinXPproSP2

And some part of log (about 300Kb per day):
