This patch was made by the following process. 1. post patch for additional pg_receivexlog synchronous mode.
2. In response to comment for the flush frequency, I revise the patch to do flush every consecutive message in reference to walreceiver. 3. The synchronization mode was necessary to reply after flush at a flush position, but --status-interval for setting at least 1 second, it was pointed out. Therefore I changed it to the patch to add the mode which the same interval flush with walreceiver, and I canceled the synchronization mode. 4. The refactor patch was offered, and there was the "--fsync-interval" option in the "pg_recvlogical" which specifies a flush interval. I changed it to the patch which did flush specified interval by the "--fsync-interval" in the same way as "pg_recvlogical". 5. Post the patch that reflects the comments centered on the document pointed out that. 6. The patch for correcting the operation at the time of specifying zero as "--status-interval" was offered. In response to it, those that modify the behavior of If you specify -1 or zero of the "fsync-interval" is this patch. Regards, -- Furuya Osamu
