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
/ cluster) is empty after this, it is
removed as well.
An empty socket directory other than /var/run/postgresql or /tmp is
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.
