Thanks, Gilles! I'll incorporate all your fixes to patchset.
Can you also benchmark conditional variable sleep? The patch "Add conditional variable to wait for next MultXact offset in corner case"?
The problem manifests on Standby when Primary is heavily loaded with MultiXactOffsetControlLock.
Thanks!
