Please find attached an updated version of this patch, where I have
extended the support of the upgrade script down to 9.5 as origin
version, as ~9.4 now fail because of cluster_name, so Cluster.pm does
not support that.  FWIW, I have created an extra set of dumps down to
9.4.

This adds proper handling for initdb --wal-segsize and
--allow-group-access when it comes to v11~, as these options are
missing in ~10.
