Also on Ubuntu lots of the Postgres utilities will obey an envvar like
`PGCLUSTER=9.5/main` to let you choose which version of
psql/pg_dump/etc. I don't know about pg_isready but it's worth a try.
Even if pg_isready doesn't follow that pattern, it is probably easy to
"teach" it. Here is how I did a similar thing for pg_config:
