I am using postges, 8.0.0
on that system , it seems that there are two databases, i am not sure if the same postmaster is used to connect to both the databases,
 
 
i am seeing these logs in postgreslog

Kinda looks like something deleted your semaphores --- does "ipcs -s"
show anything?

Stopping and restarting the postmaster should fix it, if so, but you'll
want to find out who ipcrm'd the semaphores and rap their knuckles.
