That is helpful, I have created a slightly different function that
returns an interval in the format HH:MM not sure if it will help anyone
or anyone has any suggestions to improve it:
create function hours(interval) returns varchar as 'SELECT
floor(extract(epoch from $1)/3600) || \':\' || (cast(extract(epoch FROM
$1) AS integer)%3600)/60;' language SQL IMMUTABLE;
Thanks
