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, wal, and tablespace directories, the log file, and all
configuration files that were created by pg_createcluster(1). If the
is empty after this, it is removed as well. An empty socket directory other
than /var/run/postgresql or /tmp is also removed.
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.
