But do we guarantee that old clients work with newer server versions? For example, psql docs say: "psql works best with servers of the same or an older major version. Backslash commands are particularly likely to fail if the server is of a newer version than psql itself." [1] (See Notes Section). Similarly, pg_dump docs say: "However, pg_dump cannot dump from PostgreSQL servers newer than its own major version; it will refuse to even try, rather than risk making an invalid dump." [2] (See Notes Section). It seems Sawada-San has the same question and IIUC docs suggest we don't need such compatibility, so what makes you think we need it?
