An example of how to deal with this:
CREATE OR REPLACE FUNCTION public.todatetimeoffset(ts_ timestamp with
time zone, tz_ text)
RETURNS character varying
LANGUAGE plpgsql
AS $function$
begin
--perform set_config('timezone', tz_, true /* local */);
EXECUTE 'set local timezone to ' || quote_literal(tz_);
return to_char(ts_, 'YYYY-MM-DD HH24:MI:SS.US0 TZH:TZM');
end;
$function$
select ToDatetimeOffset(now(), 'Europe/Amsterdam');
todatetimeoffset
