It works here.

Perhaps the "normal" user is a member of "pg_read_all_data".

Yours,

Don't think so:
andreak(at)[local]:5432 16.3 andreak=# REVOKE pg_read_all_data from nisse;
WARNING: role "nisse" has not been granted membership in role
"pg_read_all_data" by role "postgres" REVOKE ROLE

Any hints welcome.
