The following bug has been logged online:

Bug reference: 1363
Logged by: Jean Claude
Email address: gaudetjc (AT) neuf (DOT) fr
PostgreSQL version: 8.0
Operating system: W2K
Description: Loose connection in idle mode
Details:

I didn't found any related topic about timeout connection with a non
activity of clients. In fact the server disconnect any client after ~10
minutes of inactivity. I try it with my program that i am developping, psql
and pgadmin III. All do the same after arround 10 minutes with inactivity or
idle, the server diconnect by logging a message "unexpected EOF on client
connection".
Hoping to find out the reason or maybe a bug but all my project is in
standby now to fix this problem.
Thanks in advance for all your help
JClaude
