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'';
ALTER TABLE $tName
ADD FOREIGN KEY(key1) REFERENCES table1;
ALTER TABLE $tName
ADD FOREIGN KEY(key2) REFERENCES table2;
END IF;
RETURN ''OK'';
END;'
LANGUAGE plpgsql;"
