I think we have decided that any system we come up with now for space
reservation will be inadequate, so we will just backpatch any needed
space reservation code. Fortunately space expansion is a rare event.
And we decided we don't need a pg_class column because a custom table
will do just as well in reporting the tables that have been prepared
with reserved space.

Now that pg_migrator is BSD licensed, and already in C, I am going to
spend my time trying to improve pg_migrator for 8.4:
