You need to post your exact input and the exact output. Otherwise we're
just guessing.
My other
question is who has access to the pg_catalog.* tables?
Everybody.
And are these tables per database
or shared across PgSQL?
Most of them are per database, only a few of them are shared.
Is is true that every user can check if
he/she has access to a particular table and examine the ACL string?
Yes.
And how can I determine if a user can change permissions for other
users?
You can check the grant options available to the user.
I just worked out the query which does the job and wanted to post it so
if anyone wants in the future can refer to this thread. Here's the query:
SELECT pg_catalog.pg_class.relacl AS permissions FROM
pg_catalog.pg_class WHERE pg_catalog.pg_class.relname = 'table_name' AND
pg_catalog.pg_class.relnamespace IN (SELECT pg_catalog.pg_namespace.oid
FROM pg_catalog.pg_namespace WHERE pg_catalog.pg_namespace.nspname =
'schema_name');
