Hi
I am using postgresql 7.3.x. I am upgrating a database PostgreSQL.
The main problem is how to change field last value in sequencde which exists in database.
I created script to read this field and then I'm drop the table, do modification and i'm must change this value to another value.
But DBMS returns me message like that
ERROR: You can't change sequence relation seq_id_seq
How to do this

Documentation says:
6.11. Sequence-Manipulation Functions
select setval('some_sequence',333);

Use the setval() function?

Are you using and UPDATE to set last_value? If so, you should use the setval()
function instead.
SELECT setval('my_seq', 1234);

HI
Thanks for help I'm found this solution and this works, but I'm use
something like that
PERFORM setval(seq_name, value);
It looks better but thanks a lot
