That could be "foo.bar"."baz", or "foo"."bar"."baz", or "foo"."bar.baz", or even "public"."foo.bar.baz".  The old
behaviorseems a bit dangerous.  There may be tables with all those names, and the user may not have meant the one that
wegave them. 

You are attacking a straw man here.  To use a period in an identifier,
you have to double-quote it; that's the same in SQL or \d.

regression=# create table "foo.bar" (f1 int);
CREATE TABLE
regression=# \d foo.bar
Did not find any relation named "foo.bar".
regression=# \d "foo.bar"
              Table "public.foo.bar"
 Column |  Type   | Collation | Nullable | Default
--------+---------+-----------+----------+---------
 f1     | integer |           |          |

According to a quick test, you did not manage to break that in v14.

I do not understand why you're even questioning that.  The old
behavior had stood for a decade or two without complaints.
