Hello Osumi-san.
I have checked the latest v17 patch w.r.t. to my previous comments.
The v17 patch applies cleanly.
make check is successful.
The regenerated docs look OK.
I have no further review comments, so have flagged this v17 as "ready
for committer" - https://commitfest.postgresql.org/30/2307/

Kind Regards,
