There is a fix in current sources. I do not have a patch for 7.0.* handy, but you could probably adapt the change that was applied: http://www.postgresql.org/cgi/cvsweb.cgi/pgsql/src/backend/postmaster/postmaster.c.diff?r1=1.198&r2=1.199&f=c The additions to reaper() are the only critical part, I think. > We also seem to get a large number of the following message in our > Postmaster's log: > pq_recvbuf: unexpected EOF on client connection > Are these connected? What do the messages mean? No, those just mean that some client is disconnecting without bothering to send the "I'm done" message. It's pretty harmless from the DB's point of view. Do you have a client that crashes a lot? regards, tom lane
