Another set of comments, about the patch that adds pg_combinebackup:

Make sure all the options are listed in a consistent order.  We have 
lately changed everything to be alphabetical.  This includes:

- reference page pg_combinebackup.sgml

- long_options listing

- getopt_long() argument

- subsequent switch

- (--help output, but it looks ok as is)

Also, in pg_combinebackup.sgml, the option --sync-method is listed as if 
it does not take an argument, but it does.
