Hi all,
This patch is to add setting to send status packets after fsync to --status-interval of pg_receivexlog.
If -1 is specified to --status-interval, status packets is sent as soon as after fsync.
Others are the same as when 0 is specified to --status-interval.
When requested by the server, send the status packet.
To use replication slot, and specify -1 to --fsync-interval.
As a result, simple WAL synchronous replication can be performed.
In simple WAL synchronization, it is possible to test the replication.
If there was F/O in synchronous replication,
it is available in the substitute until standby is restored.
Regards,
