Installing only the packages:
sudo apt-get install -y postgresql-9.6 postgresql-client-9.6
postgresql-server-dev-9.6
results in a broken install on Ubuntu version 16.04 (tested on
Travis). A similar packages combination works for all the other
supported and recently unsupported versions, from 9.4 to 13.
After packages are installed the database fails to start with the error:
systemd[1]: Starting LSB: PostgreSQL RDBMS server...
postgresql[5782]: * Starting PostgreSQL 9.6 database server
postgresql[5782]: * Error: cluster_port_ready: could not find psql binary
postgresql[5782]: ...fail!
systemd[1]: postgresql.service: Control process exited, code=exited status=1
systemd[1]: Failed to start LSB: PostgreSQL RDBMS server.
systemd[1]: postgresql.service: Unit entered failed state.
systemd[1]: postgresql.service: Failed with result 'exit-code'.
Complete build log is in [1]; the complete install script is in [2].

I've tried installing the generic `postgresql-client` package too but
build fails in other amusing ways (e.g. missing clang 6.0, even if I
doubt PG 9.6 needs it).
This is being a stopper for releasing pg_repack for PG 13, so I will
temporarily remove PG 9.6 from the testing grid.
