Yeah, I don't see a difficulty on the input side, so I'm guessing
the OP is wishing Postgres would output timestamps in that format.
Sorry, none of the built-in datestyle settings quite match that.
It's easy to replicate pretty closely using to_char():

postgres=# select to_char('Jan 21 2026 5:35 PM'::timestamp, 'Mon DD YYYY HH:MI PM');
to_char
----------------------
Jan 21 2026 05:35 PM
(1 row)

But wrapping all your timestamp output columns in to_char() might be
more trouble than fixing the client-side code to accept ISO format.
