Ugh.  Well, obviously we need to get this fixed if we want CONCURRENTLY
at all :-)

Please don't post patches that aren't the commitfest item's main patch
as attachment with .patch extension.  This confuses the CFbot into
thinking your patch is the patch-of-record (which it isn't) and reports
that the patch fails CI.  See here:
https://cirrus-ci.com/github/postgresql-cfbot/postgresql/cf%2F5117
(For the same reason, it isn't useful to number them as if they were
part of the patch series).

If you want to post secondary patches, please rename them to end in
something like .txt or .nocfbot or whatever.  See here:
https://wiki.postgresql.org/wiki/Cfbot#Which_attachments_are_considered_to_be_patches?

Thanks for your interest in this topic,
