I'd have thought that this was the correct way to do it. Anyway, you
could encapsulate this in a function to make re-use easier (the
following hasn't been tested):
create function is_same_minute(time with time zone, time with time zone)
returns bool
as
$$
select
(extract(hours from $1) = extract(hours from $2))
and
(extract(minutes from $1) = extract(minutes from $2));
$$
language sql;
