From 79a4a665c046af91d4216fe69b535c429039d0d0 Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Tue, 26 Sep 2017 08:58:06 -0400 Subject: [PATCH] Fix trivial mistake in README. You might think I (Robert) could manage to count to five without messing it up, but if you did, you would be wrong.

If a scan gets ahead of cleanup, we could have the following problem: (1) the scan sees heap TIDs that are about to be removed before they are processed by VACUUM, (2) the scan decides that one or more of those TIDs are dead, (3) -VACUUM completes, (3) one or more of the TIDs the scan decided were dead are +VACUUM completes, (4) one or more of the TIDs the scan decided were dead are reused for an unrelated tuple, and finally (5) the scan wakes up and erroneously kills the new tuple. -- 2.49.0
