$0 manages a PostgreSQL Server as an HA resource.
The 'start' operation starts the PostgreSQL server.
The 'stop' operation stops the PostgreSQL server.
The 'status' operation reports whether the PostgreSQL is up.
The 'monitor' operation reports whether the PostgreSQL is running.
The 'validate-all' operation reports whether the parameters are valid.
The 'methods' operation reports on the methods $0 supports.
