The following example displays the result of the SVV\$1RLS\$1APPLIED\$1POLICY. To query the SVV\$1RLS\$1APPLIED\$1POLICY, you must have the ACCESS SYSTEM TABLE permission.

```
-- Check what RLS policies were applied to the run query.
SELECT username, command, datname, relschema, relname, polname, poldefault
FROM svv_rls_applied_policy
WHERE datname = CURRENT_DATABASE() AND query = PG_LAST_QUERY_ID();

 username | command |  datname  | relschema |          relname         |      polname    | poldefault
