Fix pg_dump to not emit invalid SQL for an empty operator class.
If an operator class has no operators or functions, and doesn't need
a STORAGE clause, we emitted "CREATE OPERATOR CLASS ... AS ;" which
is syntactically invalid. Fix by forcing a STORAGE clause to be
emitted anyway in this case.
(At some point we might consider changing the grammar to allow CREATE
OPERATOR CLASS without an opclass_item_list. But probably we'd want to
omit the AS in that case, so that wouldn't fix this pg_dump issue anyway.)
It's been like this all along, so back-patch to all supported branches.
