By and large, LGTM, though perhaps it would be appropriate to also
credit me as the reporter of the issue.
I feel it might be slightly better to highlight somewhere, either in
the commit message or in the comments, that removing the old directory
is unsafe, because if wal_level=minimal, we may have no other copy of
the data. For me that's the key point here. I feel that the commit
message and comments inside the patch explain rather thoroughly the
possible consequences of the bug and why this particular fix was
chosen, but they're not real explicit about why there was a bug at
all.
Thanks very much for working on this.
