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?

naoya=# PREPARE GETONE AS SELECT * FROM SEED WHERE ID=1;
PREPARE

naoya=# EXECUTE GETONE;

naoya=# CREATE TABLE NEW_SEED AS EXECUTE GETONE;
SELECT 1

naoya=# CREATE TABLE NEW_SEED2 AS EXECUTE GETONE WITH DATA;
ERROR: syntax error at or near "WITH DATA" at character 42

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 :-(
