The two CHECK_FOR_INTERRUPTS() additions in do_autovacuum() look correct and are well-placed at the top of each loop iteration, before any resources are acquired. I noticed there are other similar catalog scan loops in autovacuum.c that also lack CHECK_FOR_INTERRUPTS(): - The pg_database scan loop around line 1854 - The pg_class scan loop around line 3664 Should those be covered as well?
