Catch exceptions outside function - Mailing list pgsql-admin

Dear all

I ask for your help cause I can't point out the solution to my problem on PG 8.3
I would catch an exception outside any function/procedure but directly within script.


BEGIN;

-- raise an exception code

EXCEPTION
WHEN 'exception_type'
THEN ROLLBACK;

COMMIT;

is it possible with PG 8.3?


Many thanks in advance.

Roberto
