That might indeed be the most reasonable way to attack it, rather
than having to go messing about looking for a matching rule.
(Jan, any thoughts here?)

Adding a column to a core system table like pg_class is a good
exercise for the student ;-) ... it's not exactly automated,
and you have to find all the places that need to be updated.
You might want to keep notes and prepare a writeup for the
developer's FAQ.  I thought of that the last time I did something
similar, but it was only at the end that I realized I should've
been keeping notes to start with.
