There are the TZ and tz formats but they return abbreviated names, not
offsets. It's a tiny kludge, but this should do what you want:
to_char(now(), 'YYYY-MM-DD HH:MM') || to_char(extract(timezone_hour from
now()), 'S09')

This is based on the assumption that you will never have to deal with
timezones that have other than whole-hour offsets:
select * from pg_timezone_names where utc_offset::text !~ '00:00';
