Binary replication is not possible between different major versions. You can
do logical replication, using the pglogical extension:
https://github.com/2ndQuadrant/pglogical
(Although not directly related, do note that 9.6 has been past end-of-life for
nearly a year, and version 10 will reach end-of-life in November of this year.
10.17 is over a year old, and 9.6.1 is almost six years old; the most recent
versions of each are 10.22 and 9.6.24.)
