SERIAL and Primary Key

["Mike Gould" <mgould@xxxxxxxxxxxx>]

CREATE TABLE "fav5"."batchnumber" (
  "batchnumberid" SERIAL NOT NULL,
  "processtype" SMALLINT NOT NULL,
  "termloc" CHAR(3) NOT NULL,
  "batchno" INTEGER NOT NULL
) WITHOUT OIDS;

With the above table definition, is batchnumberid by default also defined as the primary key or do I still need to define a separate Primary Key constraint?
