I don't think there is anything to "fix". If the table is part of the
extension then it should not get dumped separately. I don't know enough
about PostGIS to know if there's a valid reason to want to dump that
table by itself, but if you think there is, you should take it up with
the PostGIS authors; there may be a need to adjust the way PostGIS is
packaged into an extension.
