Just to be clear and to avoid incorrect conclusion. This is the type of
scenarios I imagined about when I read your previous email, concluding
such scenarios those cannot apply per the strong assumption on
SharedRecoveryInProgress your patch heavily relies on. In short I have
no objections.

The patch called v2-0001-Change-FPW-handling.patch posted on
https://www.postgresql.org/message-id/20180412.103430.133595350.horiguchi.kyotaro%40lab.ntt.co.jp,
which is the latest version available, is a mix of the patch you are
creating for this thread and of a patch aimed a fixing an issue with
partition range handling.
