I don't see how that helps answer my problem. I know how to update a
sequence. I want to pass a value for the restart vaue that depends on a
query
- all in one statement. I would think it is a common problem i.e.
migrating
data.
use a subquery to set the value -
select setval('foo', select max(some_id) from some_table)
It's all right there in the docs that you were pointed to. We try to
encourage people to be somewhat self sufficient around here.
You need to wrap a subselect in ():
select setval('foo', (select max(some_id) from some_table));
That works in 9.1.1. No clue about previous versions off the top of
my head, but I seem to recall it doesn't work in 8.3 and prior
versions.
Thanks that did work with the parens.
I could not get to work earlier.

I prefer to do it in once select like this:
select setval('foo', max(some_id)) from some_table;

Was wrong, it definitely works in 8.3. But only with the parens.

Yes. My version without parens was just a typo. I didn't test it before sending
it
