pg_dropcluster - completely delete a PostgreSQL cluster
pg_dropcluster [--stop] cluster-version cluster-name
This program removes all files that belong to a given PostgreSQL
cluster; that includes the data directory, the log file, and all
configuration files that were created by pg_createcluster(1). If the
configuration directory (/etc/postgresql/version/cluster) is empty
after this, it is removed as well.
Usually a cluster which still has a running server attached will not be
deleted. To override this, the --stop option forces a server shutdown
before the files are removed.
