Hi.
I have a table with a serial field defined with an older version of
postgresql (ver. 7). Back then max_value was 2147483647:
select max_value from my_bid_seq ;
max_value
------------
2147483647
How can I increase it? By updating the max_value-field? This is an
older thread and may have changed:
http://archives.postgresql.org/pgsql-admin/2002-12/msg00033.php
I'm running postgresql 8.3.1.

That's the max for a regular int / serial type. You'll need to change
it to bigserial / bigint which is 64 bits/

I think you're looking for ALTER SEQUENCE.
Note that if the column it's feeding into is int4, you'd also need to
alter the column type ...
