What we really want is to be able to take that output, edit it,
and put it into another program that creates the page files anew.
Or maybe just generate new data ourselves and run it into that
program. Then, if we can take a tablespace we've created this way
and attach it to an already-running postgres system, we've got
really, really fast import/export capability.
