Hmm, when I used pg_rewind --debug with this patch the debug message
made me confused because almost database files appears with
COPY_CONFIG. Also looking at the source code comment, it says
COPY_CONFIG is aimed to configuration files. But these file are not
configuration files actually. COPY_DATA makes sense to me, but
COPY_CONFIG doesn't.

Anyway, other than that the patch looks good to me. I'd like to wait
for the Dmitory's review comment before marking this as "Ready for
Commiter".
