Hi All
Does 'COPY table FROM...' command update the last_value field of the
sequence(s) related to the table ?
Is a setval( ) function required after completion ? In this case, what's the
best command for doing that ?
Thanks

SELECT setval('sequence_name',
(SELECT MAX(column_name)
FROM table_name)
);

No. I assume you have specified values in your source
file that take the place of the sequence-supplied
values, otherwise the COPY operation would almost
certainly fail.

Yes: preferably before, if you want the sequence to be
available to other users while you are doing the
import.

I can't find the reference in the docs just now, but I
believe it's:
SELECT setval ('sequence_name', new_value);
