I’ve tried two ways - bare SELECT in autocommit mode and BEGIN; SELECT; ROLLBACK. I first described the problem in thread on pgsql-admin@ [0], there is copy-paste from psql there, but during conversation initial description was lost.
Hmm. That behavior seems unexpected to me, but I might be missing something.
Me too. That’s why I started the thread. One small detail that might have a value is that the big table being queried is partitioned into 64 inhereted tables. Now I’m trying to write a simple script to reproduce the problem, but that is not so easy because AFAIK VACUUM on master should happen while single query on standby is running and it should vacuum those rows that have not been accessed by the query on standby yet.
