No he didn't, but that's IMHO not relevant to the possibility of using
row level security. If a row level security allows a user to select a
row, that row can be selected by any query, including «select * from t».
I don't see a way to use RLS to ensure that a query can only return a
sufficiently small subset of the total rows a user has access to.
How would you do that?
