So it seems to me that we made \df consistent with \dt when in fact what we
really wanted is for it to be consistent with \d. I hadn't actually realized
that the behaviour for \d was so different from \dt myself.
The behaviour of \dt in the face of tables which shadow system tables is
actually even stranger:
postgres=# create table pg_proc (t text); CREATE TABLE postgres=# commit; COMMIT postgres=# \dt pg_proc No
matchingrelations found.
And I don't see any reason aggregates, operators, etc, shouldn't be any more
susceptible the shadowing problem.
