Hm, that'd work too. We could make initdb look at
getenv("PG_DEFAULT_SEGSIZE") or such? Otherwise it's probably not easy
to have all tests respect that.

I still would like to have at least one test that explicitly specifies a
different size so people can see if they outright break something, but
one would be enough if we had such an animal.
