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?
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

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.
