CREATE OR REPLACE FUNCTION testifinserted(text) RETURNS bool AS '
DECLARE
testtext ALIAS FOR $1;
anfr text;
BEGIN
anfr := ''SELECT bla FROM testtabelle WHERE bla = '' ||
quote_literal(testtext);
RAISE NOTICE ''%'', anfr; -- to show the request
EXECUTE anfr;

ELSE
RETURN false;
END IF;
END;
' LANGUAGE plpgsql;
test=> SELECT * FROM testtabelle;
bla
-----
muh
(1 row)
test=> SELECT testifinserted('muh');
NOTICE: SELECT bla FROM testtabelle WHERE bla = 'muh'
testifinserted
----------------
f
(1 row)
------------------------------------
WHY ????
seems like PERFORM always returns TRUE and EXECUTE always FALSE...
