I think what you probably really want is
CREATE DOMAIN datetime AS timestamptz;
or more SQL-spec-compliantly
CREATE DOMAIN datetime AS timestamp with time zone;
which essentially makes datetime a direct alias for timestamptz. The
CREATE TYPE approach makes a rowtype containing one timestamptz column,
which isn't really going to act the way you want --- for one thing,
none of the predefined functions and operators for type timestamptz
will accept it. With the DOMAIN approach, they will.
