Hello James, based on the "Specify thread msgid" message it looks like
you were trying to request a feature using the Commitfest website? That
won't work; the commitfest website is only intended as a tracker of
in-progress development work. Without a Postgres code patch, that
website doesn't help you any. What you have done amounts to hijacking
an unrelated mailing list thread, which is discouraged and frowned upon.
That said, sadly we don't have any official feature request system,
Please start a new thread by composing an entirely new message to
pgsql-hackers@lists.postgresql.org, and don't use the commitfest
website for it.

I have the feeling that this has already been discussed, but I can't
find anything useful in the mailing list archives.
