Обсуждение: Grant question
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. -- Barbara E.

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/current/interactive/sql-grant.html It speeks about granting all kind of relations, but not sequences. Just a tip. -- select 'mmarques' || '@' || 'unl.edu.ar' AS email; ------------------------------------------------------- Martín Marqués | Programador, DBA Centro de Telemática | Administrador Universidad Nacional del Litoral -------------------------------------------------------

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? arbara Lindsey wrote: > 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. > -- Barbara E.

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
