Обсуждение: pgsql function for roman2decimal?
This really feels like something that should be part of a module and not the core code.

Someone worked on this in 2017 but it was never added due to lack of
interest. I am sure it can be cleaned up and added to PG 14 if there is
demand:

If the core code already does one direction (I didn't know this) then I would agree. It seems that both would make sense to be in a separate module, due to the rarity of use, possibly just as an "exotic function" module, which would have a lower barrier of entry to adding code to.

Well, we already do the numeric to Roman conversion, so doing the
reverse seems to make sense:
SELECT to_char(335, 'RN');
to_char
