Yeah, this is clearly a version-skew problem.  pg_upgrade knows it
should say unix_socket_directory not unix_socket_directories to a pre-9.3
server, but that's going wrong somehow.

For quite some time, Red Hat shipped versions of 9.2.x that were patched
to understand unix_socket_directories not unix_socket_directory.  I would
be suspicious that the source server was one of those, except that the
cited path doesn't match where the Red Hat RPMs put it.
