Nope.
As my understanding, in a PL/pgSQL function, all statements are in ONE
transaction,
you do not need another pair of begin/end. If transaction failed, it abort
whole
thing anyway.

Subject: [SQL] PL/PGSQL question on transactions
Can you imbed BEGIN; and COMMIT; statements in the body of a pl/pgsql
function?
I am getting a parse error upon execution when I try it.
Code:
CREATE FUNCTION chitadj(integer,integer) RETURNS integer AS '
DECLARE result integer; oldamount integer;
BEGIN BEGIN; SELECT INTO oldamount chits FROM avatar WHERE avatar_id = $1;
IF oldamount IS NULL THEN RETURN -1; END IF;
IF ((oldamount < abs($2)) AND ($2 < 0)) THEN RETURN -2; END IF;
result := oldamount + $2; RETURN result; COMMIT;
END;
' language 'plpgsql';
