Um, no:
parallel group (19 tests): limit prepare copy2 plancache xml returning
conversion rowtypes largeobject temp truncate polymorphism with
without_oid sequence domain rangefuncs alter_table plpgsql
Out of curiosity, I tried a serial run (MAX_CONNECTIONS=1), which took
about 39s (with patches).

Possibly, but I know I run "make check" not "make installcheck" when I'm
testing new code. And the buildfarm, afaik, runs "make check". And,
for that matter, who the heck cares?
The important thing is that "make check" still runs in < 30 seconds on a
standard laptop (an ultraportable, even), so it's not holding up a
change-test-change-test cycle. If you were looking to prove something
else, then go for it.
