When encountering the error 0L000: Invalid Grantor
in PostgreSQL, the user should take the following actions immediately:
SELECT rolname, rolsuper, rolcreaterole, rolcreatedb, rolcanlogin FROM pg_roles WHERE rolname = current_user;
SELECT grantor, grantee, privilege_type FROM information_schema.role_table_grants WHERE table_name='your_table_name';
SELECT grantor, grantee, privilege_type FROM information_schema.role_usage_grants WHERE object_name='your_object_name';
'your_table_name'
and 'your_object_name'
with the names of the specific table or object you were trying to access or modify.SELECT table_name, table_owner FROM information_schema.tables WHERE table_name='your_table_name';
SELECT oid::regclass::text, relowner FROM pg_class WHERE oid::regclass::text = 'your_object_name';
'your_table_name'
and 'your_object_name'
with the appropriate names.ALTER TABLE your_table_name OWNER TO new_owner;
your_table_name
with the name of your table and new_owner
with the name of the new owner role.Note: These actions are direct responses to investigate and potentially resolve the Invalid Grantor
error. However, exercise caution, especially when changing ownerships or permissions, and ensure you have the right to perform these operations. If unsure, consulting with a more experienced database professional is advisable even in the absence of a designated database administrator.
