The previous para says that.

Uh, well, the chart says it via syntax, which isn't exactly the same as
stating it, and this is particularly important because it is an odd
default.
I have created an updated paragraph for that section:
http://momjian.us/tmp/pgsql/datatype-datetime.html
Note: The SQL standard requires that writing just timestamp be
equivalent to timestamp without time zone, and PostgreSQL honors that
behavior. (Releases prior to 7.3 treated it as timestamp with time
zone).
Is that an improvement?
