Attached 2 patches.
000 patch changes syntax of s_s_names from 'k(n1, n2, n3)' to 'First k
(n1, n2,n3)' for PG9.6.
001 patch adds the quorum commit using syntax 'Any k (n1, n2,n3)' for PG10.
Since we already released 9.6RC1, I understand that it's quite hard to
change syntax of 9.6.
But considering that we support the quorum commit, this could be one
of the solutions in order to avoid breaking backward compatibility and
to provide useful user interface.
So I attached these patches.
