Strictly speaking this patc doesn't introduce this fifth class of
keyword. We already had TIME in that category (and also FIRST and LAST
in a similar category following NULLS). If we have a solution for WITH
<keyword> then presumably we would implement it for WITH TIME and WITH
ORDINALITY at the same time.

In the interim I suppose we could teach pg_dump to quote any keyword
that follows WITH or NULLS pretty easily. Or just quote those four
words unconditionally.
