i have written function in which while executing it may throw error.
if the error thrown i want rollback the transaction if not i want commit.
BEGIN;
SELECT you_function(args);
...
many sql commands;

COMMIT;
that's all
if your function raises an error
whole transaction will be aborted

You could continue with this function, with an
additional cursor to get the parameters for the function. If this is a one off
thing, that you just need to do once, you could use pg_dump to get the create
function statements and then simply alter them with an re in your favorite
editor.

Greetings,
I have my DATESTYLE set to ISO MDY.
When I try to create a table with a default date of -00-00, psql says
that this is an invalid date. Why, and can (or how can I) get it to
accept -00-00 as a valid date?
Thanks,

Jeziel,
there are a couple techniques you can try, two I
like are set difference and anti-joins.
heres the set diff:
select id
from messages
except
select id
from usermessages
that will returns all id from messages not in usermessages
if ID is indexed on both
Folks,
I'm looking at using pg to be the main platform for integrating info
from other RDBMS products (particularly Oracle) as pg seems to be
the most flexible RDBMS around.
Disregarding writing to foreign products, query-plan efficiencies,
