If auto-analyze kicks in at just the right moment, it can hold a snapshot and prevent the VACUUM command in the test from removing the deleted tuples. The test needs the tuples to be removed, otherwise no half-dead page is generated. To fix, introduce a helper procedure to wait for the removable cutoff to advance, like the one used in the syscache-update-pruned test for similar purposes. Thanks to Alexander Lakhin for reproducing and analyzing the test failure, and Tom Lane for the report. Discussion: https://www.postgresql.org/message-id/307198.1767408023@sss.pgh.pa.us
