Instead of register_custom_path_provider and a CreateCustomScanPath callback, let's just provide a standard function hook in set_rel_pathlist. This is more flexible than what was previously committed, is more like the usual conventions for planner hooks, and requires less support code in the core. We had discussed this design (including centralizing the set_cheapest() calls) back in March or so, so I'm not sure why it wasn't done like this already. |
