Would it be possible to have a helper function to check this:
+ok( $node_standby->poll_query_until(
+ 'postgres',
+ qq[SELECT count(*) FROM pg_stat_activity
+ WHERE backend_type = 'checkpointer' AND wait_event = 'CreateRestartPoint' ;],
+ '1'),
+ 'checkpointer is waiting in restart point'
+) or die "Timed out while waiting for checkpointer to run restart point”;
So that we could do something like
ok(node_standby->await_injection_point(“CreateRestartPoint”,”checkpointer"));
IMO, this could make many tests cleaner.
Or, perhaps, it’s a functionality for a future development?
Thanks!
