Because, as noted before, those aren't always going to be correct.
Database files can be rewritten and recreated based on certain commands
(eg: CLUSTER).  Perhaps there's a fork that isn't, but that almost seems
like it's more painful to try and figure out than just hooking in with
the CREATE command.
