It is a patch that added the --fsync-interval option.
Interface of --fsync-interval option was referring to the "pg_recvlogical.c".

It is not judgement the flush on a per-message basis.
It is judgment at the time of receipt stop of the message.

If you specify a zero --fsync-interval make the flush at the same timing as the walreceiver .
If you do not specify --fsync-interval, you will flush only when switching as WAL files as in the past.
