The documentation states this in Notes section for psql:
"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. However, backslash commands of the
\d family should work with servers of versions back to 7.4, though not
necessarily with servers newer than psql itself."
See https://www.postgresql.org/docs/12/app-psql.html for reference.
