They are under /usr/lib/postgresql/${VERSION}/bin. This allows
multiple PostgreSQL versions to coexist on the same Debian or Ubuntu
server.

Right. This is why wrappers are installed in /usr/bin that invoke the
correct version of the executable when it is known (and a default
version when it isn't, such as when you are connecting to a remote
server). You shouldn't need to invoke anything from /usr/lib directly,
unless you are doing something particularly low level.
