Well, I wonder how many users just upgrade psql vs upgrade the server. I was

Unless you are upgrading a machine where a bunch of psql-based scripts are
running to update various remote Postgres instances with older versions, I
would guess that it is unlikely that someone is going to upgrade psql and
keep the old instance of the server on the same machine.
I just wonder how many users are using a single psql to manage multiple
server instances of different older versions.
What application, that use current copy format for fast data import? I
thing, so doing incompatible changes of copy statement syntax is very
bad idea.
The old syntax is still supported in both psql and the server but I am
not sure how many applications are relying on psql to perform a copy
operation (actually a \copy).
