Which is wrong?
I don't think either is wrong, but I guess something must be misleading, so could perhaps be improved. We're simply allocating enough space for PARTITION_ROUTING_INITSIZE but we're only initialising 1 item. That leaves space for PARTITION_ROUTING_INITSIZE - 1 more items before we'd need to reallocate the array. -- David Rowley http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
