The xlog record is already written in a critical section. Yeah, perhaps the critical section needs to be extended to cover the visibility map updates. The indexes haven't been changed at that point yet, so an index-only scan still produces the right result, but a subsequent update would fail to update the visibility map because the flag on the heap page was already cleared. -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
