Re: Disallow UPDATE/DELETE on table with unpublished generated column as REPLICA IDENTITY

Hi,

I was looking at the recently pushed code [1]. IMO the wording of some
of those new error messages of function CheckCmdReplicaIdentity() is
not quite correct.

According to my understanding, and according also to Chat-GPT:
------
The sentence "Replica identity consists of an unpublished generated
column." implies that the entire replica identity is made up of an
unpublished generated column and nothing else.

This is because the phrase "consists of" typically indicates a
complete composition, meaning that the replica identity is exclusively
composed of the unpublished generated column in this context.
------

IIUC, these errors are intended for when there is *any* unpublished
generated column found in the RI, and the RI might also have other
columns in it generated or otherwise. So, I think those error messages
saying "consists of" should be reworded like below, or similar:
* errdetail("Replica identity includes an unpublished generated column.")));
* errdetail("Replica identity has one or more unpublished generated
columns.")));
* errdetail("One or more unpublished generated columns are in the
Replica identity.")));
* ...
