[pengbo]

In PostgreSQL 9.6, in COPY query copy the output of an
INSERT/UPDATE/DELETE ... RETURNING query is allowed.

In Pgpool, all of the (COPY...TO... ) was send to either primary node
or load balance node. Sometimes it causes a error.
To fix that, the query (COPY (UPDATE | INSERT | DELETE ... RETURNING ...) TO ...)
is only sent to primary node.
