It doesn't support compression nor restore reordering like the custom
format, so I'm having trouble seeing why it still exists (at least without
a doc warning that it's obsolete).

I've never used that restore.sql, so I can't say how useful it is,
especially since it requires editing $$PATH$$.  Should be mentioned in
the docs if that file is still relevant.
