I believe we hashed this out when we added add_missing_from back in 7.3.

In any case, yes, making that kind of query fail is intentional. So it should
go in the release notes as a warning. Suggested text:

====================
add_missing_from now defaults to "true". This means that queries such as the
following:
SELECT pg_class.*;
DELETE FROM table_1 WHERE table_2.fk = table_1.key AND table_2.col3 = TRUE;
... will no fail with default settings. Either set add_missing_from to TRUE
to re-enable them, or modify your application to support the correct syntax,
such as the new DELETE FROM ... USING (see below).
====================
