I agree with Tom that this should be changed; I'm just arguing that we
might well need a backwards-compatibility solution for a while. At the
very least we'd need to make this change very
One problem with removing justify_hours() is that this is going to
return '24:00:00', rather than '1 day:

Jim,
I agree in general, except most languages have terrible support for
time/date data, so I can see a much bigger case for the database being
able to do it (and it's not like we'll be removing justify_*). Be that
as it may, there are probably apps out there that will break if this is
just

The documentation for to_char states that:
|to_char(interval)| formats HH and HH12 as hours in a single day, while
HH24 can output hours exceeding a single day, e.g. 24.
However I can not get it to work with time intervals that span more than
1 day.

Considering how late it is in the cycle, perhaps the change in
behavior should come in 8.3.
Yeah, there's not really enough time to think through the consequences
now. I'd like to experiment with it for 8.3 though.
