Thanks for updating the patch.

Out of curiosity, I tried to merge the pub_collist_contains_invalid_column()
and replident_has_unpublished_gen_col() functions into a single function to
evaluate if this approach might be better.

As shown in the attached diff, it reduces some code redundancy *but* also
introduces additional IF conditions and parameters in the new combined
function, which might complicate the logic a bit.

Personally, I think the existing V10 patch looks good and clear. I am just
sharing the diff for feedback in case others want to have a look.

Best Regards,
Hou zj
