Postgresql does not allow transactions to be started/stopped inside of a
backend function. It does support savepoints which do allow work to be
saved and rolled back to, but the function call is still wrapped in an
outer transaction. For the example above leaving the BEGIN
TRANSACTION/COMMIT off may give you the behavior desired (because the
query itself is wrapped in a transaction).
