  1. SELECT currval('SEQ') broken?

    Michael J. Rogan <mrogan@fpelectronics.com> — 1998-02-25T17:01:24Z

    Hello

I like the added security of 6.3 however how do you grant access to 
SELECT currval('SEQ') AS id
I get a permission error on seq.currval?

I figured out how to use CVSUP so I am grabbing the latest version.

If this is fixed in it then great otherwise any ideas?

  2. Very nice... Solaris/Sparc works...

    Compiles, installs and tests cleanly...regression test results are in
src/test/regress/regression.Solaris-Sparc for anyone wanting to look at
the variances...

I don't remember - did we NO_ACCESS to a table for public
as default or not ?
If yes then you have to GRANT permissions on sequences...

    We did so. Default is now NO_ACCESS for public but SELECT
    granted for public on IsSystemRelationName() where no
    explicit ACL is set. So all tables and views prefixed pg_
    are readable by default and must still be revoked if you
    don't want them public readable. All other tables and
    views are private.

    Checked that and it works. The creator of the sequence is
    the owner and can do anything by default (superuser too). 

    GRANT SELECT ON seq permitts to get currval() from sequence.

    GRANT SELECT, UPDATE ON seq permitts to get nextval().


    Great to see that new security code works also for an area
    that we didn't thought about.
