What do you mean by "result is 0"? Is it "INSERT 0 0" that you're
referring to?
You reported this for 9.6.9 which doesn't have native partitioning. So,
you may have set up a trigger on the parent table to redirect INSERT on it
to INSERT into child tables / partitions. If that's so, then because of
such a trigger, nothing would be actually inserted into the parent table,
so the result is INSERT 0 0.

If you tried to use native partitioned table (CREATE TABLE with PARTITION
BY clause) in Postgres 10, then this shouldn't happen. Inserts into
parent are still redirected to child tables / partitions, but no triggers
are involved, so the result shows the actual count of rows inserted. For
example, if you insert 1 row into the partitioned table (parent), you will
get INSERT 0 1 as a result.
But if you didn't use native partitioned table, but used the same old
method of using triggers as 9.6, you will see the same behavior as
described above for 9.6.
