Yeah, it's likely to break every week or more often.

You have a few options:

0) resolve the conflict yourself;

1) apply the patch to the commit that the authors sent it against, or
some commit before the conflicting file(s) were changed in master.  Like
maybe "git checkout -b 64bitxids f66d997fd".

2) Use the last patch that cfbot successfully created.  You can read the
patch on github's web interface, or add cfbot's user as a remote to use
the patch locally for review and/or compilation.  Something like "git
remote add cfbot https://github.com/postgresql-cfbot/postgresql; git
fetch cfbot commitfest/39/3594; git checkout -b 64bitxids
cfbot/commitfest/39/3594".  (Unfortunately, cfbot currently squishes the
patch series into a single commit and loses the commit message).

You could also check the git link in the commitfest, to see if the
author has already rebased it, but haven't yet mailed the rebased patch
to the list.  In this case, that's not true, but you could probably use
the author's branch on github, too.
