Sounds reasonable, but my comments were about this commit, not the one
that happened on Saturday. This patch was posted about 32 hours ago, and
the commit need not have taken place yet. If I had posted such a patch
and committed it knowing other work is happening in that area we both
know that you would have objected.

It's not actually a major issue, but at some point I have to ask for no
more commits, so Fujii and I can finish our patches, compare and
contrast, so the best ideas can get into Postgres.
