My suggestion was a bit ambiguous, sorry for the confusion.

The "Git link" is just an annotation - cfbot doesn't try to do anything with
it[0] (but cirrusci will run the same checks under your github account).
What I meant was that it doesn't seem imporant to send rebases multiple times
per week if there's been no other changes.  Anyone is still able to review the
patch.  It's possible to build it by applying the patch to a checkout of the
postgres tree at the time the patch was sent.  Or by using the git link.  Or by
checking out cfbot's branch here, from the last time it *did* apply.
https://github.com/postgresql-cfbot/postgresql/tree/commitfest/38/3594

[0] (I think cfbot *could* try to read the git link, and apply patches that it
finds there, but that's an idea that hasn't been proposed or discussed.  It'd
need to know which branch to use, and it'd need to know when to use the git
link and when to use the most-recent email attachments).
