This is similar to a bug report that has been sent a couple of months back: http://www.postgresql.org/message-id/1402313245515-5806482.post@n5.nabble.com Here is explained why it may happen because of the visibility map code: http://www.postgresql.org/message-id/5395AB77.4080209@vmware.com But as of now, there have been no fixes submitted for that. As that's not the first bug report in the area, should we hasten a patch here? I don't mind working on that if that's necessary. Just that I won't be as fast as someone more familiar with the VM code :) > PS: > PostgreSQL 9.2.6 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.7.2-5) 4.7.2, 64-bit You should update to latest 9.2 version, which is now 9.2.9.
