PostgreSQL binaries under /usr/lib, why?

Hello

Why are many postgres binaries in ubuntu under /usr/lib/postgresql?

According to FHS-2.3, /usr/lib includes object files, libraries, and
internal binaries that are not intended to be executed directly by
users or shell scripts.

Almost all postgres binaries used directly by users are under
/usr/lib/postgresql

I am just wondering because is not the first time we have to help
ubuntu users having problems locating the postgres binaries.
(Including myself the first time I installed postgres in a ubuntu machine)

Is the future apt.postgresql.org service also going to use this
directory for postgres binaries?

Thanks in advance.
regards,
