One thing we should do is have pg_regress.c, not the Makefile,
select the default port to use. The concatenate-5 behavior is
just not intelligent enough.
How about something like this, constructing a port number from the
version and a timestamp? We could also take 2 more bits from the
version and give it to the timestamp, which would make this a bit safer,
I think.
