Re: How to determine what is preventing deleting a rule

> How can I find out what this object is?
This query might help if the object is a table:

SELECT c.relname as table,
a.rolname as owner,
c.relacl as permits
FROM pg_class c
JOIN pg_authid a ON ( a.OID = c.relowner )
WHERE relname NOT LIKE 'pg_%'
AND relname NOT LIKE 'information%'
AND relname NOT LIKE 'sql_%'
AND relkind = 'r'
AND a.rolname = '<the_owner_with_problem>'
ORDER BY relname;

Since you have not stated the PostgreSQL version, I can only
assure you this will work for 9.6 and below.
