Thanks!.

I also reproduced this delay in case of full output buffers. It has already
been fixed in the latest patch.
I think in your case, the 26-second wait was due to walsender falling asleep
at wal_sender_timeout / 2 seconds after receiving the shutdown request.
The issue should have been fixed in the patch (see WalSndComputeSleeptime).
