Oh, I got it now.  Thanks.  The revised patch is attached.  The only modified file is pg_ctl.c.  The patch worked as
expected.

It is regrettable that I could not make it in time for PG 10, but I'd appreciate it if you could review and commit this
patchearly in PG 11 while our memory is fresh.  Thank you for your patience.  I'll create an entry in the next CF
soon.

Regards
Takayuki Tsunakawa
