This isn't correct --- timestamp has meant timestamp without time zone
for a long time (since 7.3 I believe). Once upon a time it worked like
you show here, but we changed it specifically because the SQL spec says
that WITHOUT TIME ZONE is the default.
In the case of TIME, that's a good default; in the case of TIMESTAMP
not so much, but we're stuck with it because the spec says so.
