Hi Joseph,
I stumbled upon this requirement a few times. So I started working on
this support in my spare time as a hobby project to understand
horology code in PostgreSQL. This was sitting in my repositories for
more than an year. Now that I have someone else showing an interest,
it's time for it to face the world. Rebased it, fixed conflicts.

PFA patch implementing infinite interval. It's still WIP, there are
TODOs in the code and also the commit message lists things that are
known to be incomplete. You might want to assess expected output
carefully

The patch uses both months and days together to avoid this problem.

Please feel free to complete the patch, work on review comments etc. I
will help as and when I find time.
