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:
