Unfortunately, I just found out that on a slow enough machine
(prairiedog's host) there *is* some variation in when that test's
notices come out. I am unsure whether that's to be expected or
whether there's something wrong there --- Peter, any thoughts?
What I will do for the moment is remove the client_min_messages=WARNING
setting from isolationtester.c and instead put it into
insert-conflict-specconflict.spec, which seems like a saner
way to manage this. If we can get these messages to appear
stably, we can just fix that spec file.

Maybe we could just log the lengths of the strings... if there's
anything broken, we could expect that the decompressed output
would be a different length.
