hm, one might argue, that if the use case 'pg_isready -d database' is 
mentioned in the manual this could be seen as the aspiration, or maybe 
even commitment to that feature.
Even the description of pg_isready --help mentions a "connection check 
to a database", not a cluster.

Do I misinterpret the manual/help? If that was the case my next question 
was ... what is the purpose of the option -d, --dbname=DBNAME ?

all best ... Gunnar
