template0 shouldn't need to be dumped, since it's always supposed to be
virgin initdb data.  template1 may need to be dumped if you have any
site-local additions in it.  pg_dumpall gets these considerations right.

As for dropping, the system won't let you do it unless you go in and
hand-hack pg_database's datistemplate flags.  I have actually tested
dropping template1 and recreating it from template0, which I suppose
someone might want to do if they mess up template1 badly enough.
If you drop template0, you no longer have a guaranteed virgin database
to use as a reference, but perhaps that doesn't bother you.

Send 'em to pgsql-patches, I guess.
