You can't use ROLLBACK inside a plpgsql function. I agree that this
error message leaves something to be desired, though.
[ ... sounds of hacking ... ]
Now it says

regression=# select test();
ERROR: cannot begin/end transactions in PL/pgSQL
HINT: Use a BEGIN block with an EXCEPTION clause instead.
CONTEXT: PL/pgSQL function "test" line 5 at SQL statement
regression=#

That might still leave you a bit confused, since you *were* using
an EXCEPTION clause, but offhand it seems about the best we can do.
