Nah, I take that back --- I was worried that XidInMVCCSnapshot might say it was still running when it wasn't, but we never apply XidInMVCCSnapshot to XIDs that we haven't already determined to be committed, so it doesn't matter. It's still a bad idea though. Let me go respond to your -hackers post (which arrived here after the other one). regards, tom lane ---(end of broadcast)--- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq

And I didn't mess with XidCacheRemoveRunningXids, other than removing the latestCompletedXid updating.
