Hi Shubham/Shlok.
FYI, there is some other documentation page that mentions generated
column replication messages.
This page [1] says:
"Next, the following message part appears for each column included in
the publication (except generated columns):"
But, with the introduction of your new feature, I think that the
"except generated columns" wording is not strictly correct anymore.
IOW that docs page needs updating but AFAICT your patches have not
addressed this yet.
