[pgpool-general: 1777] replication method

[Garry]

Does anyone have any recommendations as to whether to use Pgpool 
replication or Postgres streaming replication? We need to have a system 
in place where a db server can fail without any users being affected by 
the fail. The application has around an 80:20 split read/write. We will 
be using Pgpool for load balancing etc. in either case.
Thanks
