You need to use EXECUTE on all statements dealing with the table
you are creating and dropping, but there is an issue that I don't
know of a direct way to select into a field with EXECUTE apart from
what I do below.
CREATE OR REPLACE FUNCTION test() RETURNS BOOLEAN AS '
DECLARE
n INTEGER;
r RECORD;
BEGIN
EXECUTE ''CREATE TEMP TABLE temp1 (MyField INTEGER)'';
EXECUTE ''INSERT INTO temp1 VALUES(8);'';
FOR r IN EXECUTE ''SELECT MyField FROM temp1 LIMIT 1'' LOOP
n := r.MyField;
END LOOP;
RAISE NOTICE ''%'',n;
EXECUTE ''DROP TABLE temp1'';
RETURN TRUE;
END;' LANGUAGE 'plpgsql';

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
