pg_ctl is normally present in /usr/lib/postgresql/<version>/bin on a debian
system. If that is gone, somebody removed it, or you didn't install the
"postgresql-9.4" package which provides it. On a 9.4 system:

$ dpkg -S /usr/lib/postgresql/9.4/bin/pg_ctl
postgresql-9.4: /usr/lib/postgresql/9.4/bin/pg_ctl

You could try reinstalling the postgresql-9.4 package and see if it comes
back. The rest of the binaries in that directory seems to be from
postgresql-9.4-client though -- have you actually by mistake uninstalled
the server package completely?

As in, that directory is supposed to have the "postgres" binary which is
the database server and it's not there. So there is no wonder it's not
starting...
