Re: 8.1 removed functions

Hi Tom,

With PG 8.0 I was using a query using makeaclitem() and aclcontains()
to extract permissions. Here is a sample query for database
permissions ...

SELECT
((grantee.name)::character varying) AS grantee,
((nc.datname)::character varying) AS database,
(pr."type") AS privilege_type,
(
CASE
WHEN aclcontains(nc.datacl, makeaclitem(grantee.usesysid,
grantee.grosysid, u_grantor.usesysid, pr."type", true))
THEN 'YES'::text
ELSE 'NO'::text
END) AS is_grantable,
('NO') AS with_hierarchy
FROM
pg_database nc,
pg_user u_grantor,
((((( SELECT pg_user.usesysid, 0, pg_user.usename FROM pg_user )
UNION ALL
( SELECT 0, pg_group.grosysid, pg_group.groname FROM pg_group
)
)) UNION ALL ( SELECT 0, 0, 'PUBLIC' ) )) grantee(usesysid, grosysid,
name),
((((( SELECT 'CREATE' ) UNION ALL ( SELECT 'TEMP' ) )) UNION ALL (
SELECT 'USAGE' ) )) pr("type")
WHERE
aclcontains(nc.datacl, makeaclitem(grantee.usesysid, grantee.grosysid,
u_grantor.usesysid, pr."type", false))
AND (grantee.name = 'postgres'::name)

What is the recommended manner to extract object permissions for 8.1
now that these functions are not available?

regards,
