Here are updated patches. I left off the final PERIODs patch because it still has some conflicts
with the new NOT NULL constraints work. I'll soon an update with that soon.

Thanks!

Done. The reason I didn't do this before is because we need the opclass, not just the am. I put an
explanation about that into the function comment. If that's a problem I can undo the change.

Done.

Okay, that makes sense. I changed that for the FOR PORTION OF bounds expression. I still need to get
the rangetype name and namespace to look up its constructor function. Even if I built another FuncExpr
myself there, I don't see any way to get the constructor oid without calling SearchSysCache3(PROCNAMEARGSNSP, ...).
So I'm still doing type oid -> type name -> func oid.

Done.

Yes, everything here was addressed in my v41 patches (sent 2024-10-21).

Rebased to 4c4aaa19a6.
