What kind of grant do you need to give a user so that they can have
permission to do a "SELECT nextval(ID)" on a sequence?
I granted the user SELECT,UPDATE,INSERT,DELETE on all the tables,
including the one that has the sequence, but the sequence query is
failing on permissions.

You have to give him grant permissons on the sequence, not only the table, as when
you do a nextval(´sequece_name´) you are updating the value of the sequence.

P.D.: Could there be some extra docs about this in the GRANT command manual:

http://www.postgresql.org/docs/curre...sql-grant.html

It speeks about granting all kind of relations, but not sequences. Just a tip.

Sequences have permissions separate from tables. I believe you need
update access to call nextval or setval on a sequence. This should
be described in the documention on the GRANT command.

Yay! It works.
Thank you.

I think you should provide an explicit grant (all) on the sequence as
well. The Sequence is an object that is distinct from the table that uses
it.

What permission does a user need to have to query the pg_ tables
(pg_attribute, pg_class, etc) ? Do they require special permissions?

What kind of queries? Read or Write?

Users have permission to read from most catalog tables. One they can't read
for security resons is pg_shadow:

prueba=> select * from pg_shadow;
ERROR: pg_shadow: permission denied
