Found a solution:
-- my_constraint(0) = turn off constraint
-- my_constraint(1) = turn ON constraint
CREATE OR REPLACE FUNCTION my_constraint(INTEGER)
RETURNS VARCHAR AS 'DECLARE cmd VARCHAR;BEGIN IF $1 = 0 THEN RAISE NOTICE ''Turning OFF
constraints''; cmd := ''ALTER TABLE $tName DROP CONSTRAINT "$1"''; EXECUTE cmd; cmd := ''ALTER
TABLE$tName DROP CONSTRAINT "$2"''; EXECUTE cmd; ELSE RAISE NOTICE ''Turning ON constraints'';
ALTERTABLE $tName ADD FOREIGN KEY(key1) REFERENCES table1; ALTER TABLE $tName ADD FOREIGN
KEY(key2)REFERENCES table2; END IF; RETURN ''OK'';END;'LANGUAGE plpgsql;"
