BTW, decent regression tests could be written without the need to create
enormous tables if the minimum rel size in create_plain_partial_paths()
could be configured to something less than 1000 blocks. I think it's
fairly crazy that that arbitrary constant is hard-wired anyway. Should
we make it a GUC?
