In section 5.5.1.3 the following paragraph has a couple of typos:
Time stamp types exist as timestamp [ (p) ], timestamp [ (p) ] without
time zone and timestamp [ (p) ] without time zone. A plain timestamp
is equivalent to timestamp without timezone.
timestamp [ (p) ] without time zone is repeated twice in the list and
timestamp [ (p) } with time zone wasn't listed. The last sentence uses
"timezone" instead of "time zone".
