Even in 9.2 where -x option was added firstly, I confirmed that
I could pass the .backup file name including the extension to
pg_archivecleanup program. So I'm wondering if the warning in
question was incorrect from the beginning...
Or am I missing something?
In the past thread of -x option patch, I found the following
Robert comment. This makes me think that we unfortunately failed to
notice his comment and finally added the unnecessary warning into
the document.

Also, I'm wondering about this warning in the documentation:
+ extension added by the compression program. Note that the
+ <filename>.backup</> file name passed to the program should not
+ include the extension.
IIUC, the latest change you made makes that warning obsolete, no?
[rhaas pgsql]$ contrib/pg_archivecleanup/pg_archivecleanup -d -x .gz .

pg_archivecleanup: keep WAL file "./000000010000000000000010" and later
