Creating a temporary table isn't working

Good Morning All!

Really simple question.
I put in the following command and I get a parse error but when I get rid of
the optional TEMP it works okay.  The docs seem to say this is how its done.

gammamatrix=> CREATE TEMP TABLE Start (VatiID int NOT NULL, TrimID int,
BodyID int, GVWRID int, DrivetrainID int, EngineID int, TransID int , FuelId
int);
ERROR:  parser: parse error at or near "temp"

Any help would be greatly appreciated.
