Makes sense. One thing I was still wondering is if it wouldn't be
easier to wrap all queries in "copy (select whatever) to stdout
(format json)" automatically when the -J flag is passed psql. Because
it would be nice not to have to implement this very similar logic in
two places.
But I guess that approach does not work for commands that don't work
inside COPY, i.e. DML and DDL. I'm assuming your current patch works
fine with DML/DDL. If that's indeed the case then I agree it makes
sense to have this patch. And another big benefit is that it wouldn't
require a new Postgres server function for the json functionality of
psql.
