Log Message:
-----------
Improve plpgsql's RAISE command. It is now possible to attach DETAIL and
HINT fields to a user-thrown error message, and to specify the SQLSTATE
error code to use. The syntax has also been tweaked so that the
Oracle-compatible case "RAISE exception_name" works (though you won't get a
very nice error message if you just write that much). Lastly, support
the Oracle-compatible syntax "RAISE" with no parameters to re-throw
the current error from within an EXCEPTION block.
In passing, allow the syntax SQLSTATE 'nnnnn' within EXCEPTION lists,
so that there is a way to trap errors with custom SQLSTATE codes.
