I still don’t fully understand why is it so (the problem occurs while running only one SELECT-statement in READ COMMITED so only one snapshot is taken), but if is expected behavior shouldn’t the documentation mention that using READ COMMITED (which is the default) you may still get conflicts with recovery while using replication slots?
Are you doing BEGIN / one or more SELECT statements / END?
Or just a bare SELECT with no explicit transaction control?
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.
