Well that would make more sense of things. I had removed and re-installed the postresql-common package:
and thought that it would leave the main PG package in place. But perhaps I was wrong. I’ll follow Tom’s advice and just re-install everything (saving the old data directory) and hope the new installation can use the old data data directory.
One question about this approach though: the Debian package installation automatically initializes the new data directory and starts PG. If I shut it down and copy the old data directory into the newly installed one, will there be an xlog issue?

As I mentioned, this Debian package removes pg_ctl from the bin directory and instead attempts to wrap the pg_ctl functionality in a perl script so that the PG process is integrated with systemd. I really wish they hadn’t, and it’s part of the reason I’m where I’m at.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_ctlpostgresql-9.4: /usr/lib/postgresql/9.4/bin/pg_ctlYou 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...--
