I also tried below:
techdb=# revoke all ON techtable from public;
REVOKE
techdb=# select pc.relname, pc.relacl from pg_class pc, pg_namespace pn
where pc.relnamespace=pn.oid and pn.nspname='techdb' and
pc.relname='techtable';
relname | relacl
-----------+-----------------------------
techtable | {postgres=arwdDxt/postgres}
(1 row)
techdb=# GRANT SELECT (description), UPDATE (description) ON techtable TO
user1;
GRANT
techdb=# select pc.relname, pc.relacl from pg_class pc, pg_namespace pn
where pc.relnamespace=pn.oid and pn.nspname='techdb' and
pc.relname='techtable';
relname | relacl
-----------+-----------------------------
techtable | {postgres=arwdDxt/postgres}
(1 row)
Please note that giving select permission on description column doesn't made
any difference in permissions set pf pg_namespace,
techdb=# \q
> psql -h techdbdev1.lon -d techdb -E
psql (8.4.1)
Type "help" for help.
techdb=> select * from techtable;
ERROR: permission denied for relation techtable
techdb=>
...and it gives permission denied..!
Please help me to sort this out.
Thanks.
