Back-patch relevant parts of these commits: 30717637c Fix isolationtester race condition for notices sent before blocking ebd499282 Don't drop NOTICE messages in isolation tests a28e10e82 Indicate session name in isolationtester notices This ensures that older versions of the isolationtester will handle NOTICE/WARNING messages the same way as HEAD and v12 do. While this isn't fixing any critical problem right now, it seems like a prudent change to prevent surprises (like we had yesterday...) with back-patches of future isolation test changes. Back-patch as far as 9.6. Due to the significant changes we made in isolationtester in 9.6, back-patching isolation tests further than that is going to be risky anyway; besides, this patch doesn't apply cleanly before that.
