Refined #107845

Thanks! These changes look good to me :-)

Can you rebase and squash this into a single commit?

@dsnopek Rebase and squash complete. Fixed the merge conflict with the recent changes as well.

Thanks!

I noticed two mistakes in your latest changes (see below) but they are probably due to some other mistakes from #118214 which incorrectly say that classdb_register_extension_class6 and classdb_construct_object3 were "since" 4.6, but actually, those are since 4.7

Would you mind updating those in your PR as well?

[Mister-Ky]

@dsnopek Done!

[Mister-Ky]

I have corrected "since" from another PR as you said

[dsnopek]

Thanks! This looks great to me :-)

I've added the bug label and switched this to the 4.7 milestone, because this now also fixes some mistakes from #118214 which should be included in the 4.7 release
