Well, the system catalogs don't change terribly often, so it's not
like a lot needs to be done. We'd hoped to get them into core, but
that didn't pan out. Theoretically, we should be making the views
look more like information_schema, but no one's gotten to it yet.

Well, there's nothing that says you have to use information_schema.
You can always query the catalog tables directly. Even if you don't
want to use newsysviews as-is, the code there should be very helpful
for doing that.
There is no ability to put triggers on DDL, so the best you could do
with your caching table is to just periodically update it.
