You could mark the built-in cast as assignment-only (I wouldn't
recommend setting it to implicit, as it's not clear what cases
that might break).
d1=# create table foo (f1 bool);
CREATE TABLE
d1=# insert into foo values(1);
ERROR: column "f1" is of type boolean but expression is of type integer
HINT: You will need to rewrite or cast the expression.
d1=# update pg_cast set castcontext = 'a' where castsource = 'int'::regtype
d1-# and casttarget = 'bool'::regtype;
UPDATE 1
d1=# insert into foo values(1);
INSERT 0 1
Unfortunately this is something you'd have to do over after any database
reload, because pg_dump won't preserve changes to the definitions of
built-in objects.
