Creation of a table with dynamic name from inside a pgpsql function

Hi,

i have tried to create a table with a name specified by a calling parameter of
a pgsql function. Something like this:
CREATE FUNCTION test (varchar) RETURNS TEXT AS '
DECLAREtable_name ALIAS FOR $1;query_string varchar;

BEGIN
query_string:= ''CREATE TABLE temp1 AS SELECT * FROM ''||
quote_ident(table_name) || '' WHERE (hsp_rank=1 AND hsp_evalue<=0.001)'';
RAISE NOTICE ''Query: %'',query_string;
EXECUTE query_string;
RETURN table_name;
END;
' LANGUAGE 'plpgsql';

with the following result:

prod2_db=# select test('blasthits_obj_174_q122_db123');
NOTICE:  Query: CREATE TABLE temp1 AS SELECT * FROM
blasthits_obj_174_q122_db123 WHERE (hsp_rank=1 AND hsp_evalue<=0.001)
ERROR:  EXECUTE of SELECT ... INTO is not implemented yet
prod2_db=#

i read in the docs, that an SELECT INTO is not fully supported, but how can i
solve this problem ? Any idea or workaround ?
