Thread: [COMMITTERS] pgsql: Allow parallelism in COPY (query) TO ...;

Allow parallelism in COPY (query) TO ...;

Previously this was not allowed, as copy.c didn't set the
CURSOR_OPT_PARALLEL_OK flag when planning the query. Set it.

While the lack of parallel query for COPY isn't strictly speaking a
bug, it does prevent parallelism from being used in a facility
commonly used to run long running queries. Thus backpatch to 9.6.
