#include <db.h> int DB_SITE->remove(DB_SITE *site);
         The DB_SITE->remove() method removes the
         site from the replication group.  If called at the master site,
         repmgr updates the membership database directly. If called from a
         client, this method causes a request to be sent to the master to
         perform the operation. The method then awaits confirmation.
    
The DB_SITE handle must not be accessed again after this method is called, regardless of the return value.
         The DB_SITE->remove() 
            
                  method returns a non-zero error value on failure and 0 on success.
