Обсуждение: pg_catalog permission problem

I'm using Postgres 7.4.  I have a database called tracking and user called
test5.  From the Red Hat command line test5 can psql tracking and run:

    SELECT * FROM Customers;

Not surprisingly, a list of customers is shown.

I have a Visual Basic application is accessing the same database.  The same
user can open a connection to the same database.  When the same query is run
the following error is thrown from Postgres:

    permission denied for schema pg_catalog

With the connection to the database still open, I've run the foloowing query:

    SHOW search_path;

And the following error message is returned:

    permission denied for relation pg_type

Setting this user to usesuper=True in the pg_shadow table enables everything
to work correctly.  But I obviously don't want to do that.

I've also tried:

    GRANT ALL ON SCHEMA pg_catalog TO test5;
and
    GRANT ALL ON SCHEMA pg_catalog TO PUBLIC;

and that doesn't seem to work.

Any ideas on where my permissions problem is?  Is this something I missed in
the Postgres install?  Could the Postgres process be running under an
inccorect user id?

I'd appreciate any help.  Thanks...

Hmmm ... better find out what queries your VB application is really
issuing.  Turning on query logging in postgresql.conf might be
illuminating.
