A.93. Release 3.7.13

Disallowing the quorum aware failover option for the native replication mode. (Muhammad Usama)

In native replication mode, Pgpool-II. is responsible for replicating the data on all backend nodes, and if a node becomes quarantined then Pgpool-II stops sending the writes to that node. This is dangerous since it can cause data inconsistency.

So as per the discussion, we reached the conclusion to disallow failover_when_quorum_exists with the native replication mode so that backend node should never get into quarantine when Pgpool-II is configured in the replication mode.
