"CREATE TABLE table_name AS EXECUTE name WITH DATA" becomes syntax error.

Hi,

Accroding to http://www.postgresql.org/docs/9.1/interactive/sql-createtableas.html ,
"CREATE TABLE table_name AS EXECUTE name WITH DATA" seems a right syntax,
but,this statement becomes a SYNTAX ERROR.
Is this a specification?

Order of execution?

Example from link above:
PREPARE recentfilms(date) AS
  SELECT * FROM films WHERE date_prod > $1;
CREATE TEMP TABLE films_recent WITH (OIDS) ON COMMIT DROP AS
  EXECUTE recentfilms('2002-01-01');

So for your case:
CREATE TABLE NEW_SEED2  WITH DATA AS EXECUTE GETONE;

Hmm ... it looks like WITH [NO] DATA is actually only implemented for
the query = SelectStmt case, not the query = ExecuteStmt case.  We need
a less klugy implementation to support EXECUTE :-(
