Renaming applications shouldn't be a problem unless they have to be
moved from one binary package to another. I assume all packagers ship
all client/server binaries in one package, respectively (and not e.g. a
dedicated postgresql-11-pg_test_fsync package), this should only be a
matter of updating package metadata.

In any case, it should be identical to the xlog->wal rename.
