Re: How to get whether user has ALL permissions on table?

Okay I got to know from
http://www.postgresql.org/docs/8.4/interactive/functions-info.html that the
has_table_privilege returns true if any of the listed privilege is held.
Then how can I find whether user has all the specified permissions or not?

>From http://www.postgresql.org/docs/8.4/interactive/functions-info.html

has_table_privilege checks whether a user can access a table in a particular
way. The user can be specified by name or by OID (pg_authid.oid), or if the
argument is omitted current_user is assumed. The table can be specified by
name or by OID. (Thus, there are actually six variants of
has_table_privilege, which can be distinguished by the number and types of
their arguments.) When specifying by name, the name can be schema-qualified
if necessary. The desired access privilege type is specified by a text
string, which must evaluate to one of the values SELECT, INSERT, UPDATE,
DELETE, TRUNCATE, REFERENCES, or TRIGGER. Optionally, WITH GRANT OPTION can
be added to a privilege type to test whether the privilege is held with
grant option. Also, multiple privilege types can be listed separated by
commas,* in which case the result will be true if any of the listed
privileges is held.* (Case of the privilege string is not significant, and
extra whitespace is allowed between but not within privilege names.)
Could anyone please help me out.

Thanks,
Dipti
