Get rid of copy_partition_key
That function currently exists to avoid leaking memory in
CacheMemoryContext in case of trouble while the partition key is being
built, but there's a better way: allocate everything in a memcxt that
goes away if the current (sub)transaction fails, and once the partition
key is built and no further errors can occur, make the memcxt permanent
by making it a child of CacheMemoryContext.
