This will (re)create: This will (re)create:
- Two tables `floats` and `points`. - Four tables: `floats`, `floats_indexed`, `points`, and `points_indexed`.
- Three procedures `generate_coords`, `float_coords_within_radius`, - Nine procedures: `generate_coords`, `float_coords_within_radius`,
`hybrid_coords_within_radius`, and `point_coords_within_radius`. `float_indexed_coords_within_radius`, `hybrid_coords_within_radius`
- Two functions `haversine` and `haversine_alt`. `hybrid_coords_within_radius_point`, `hybrid_indexed_coords_within_radius`,
`hybrid_indexed_coords_within_radius_point`, `point_coords_within_radius`,
`point_indexed_coords_within_radius`
- Two functions: `haversine` and `haversine_alt`.
And then will generate and insert 1,000,000 random coordinates into `floats` and And then will generate and insert 1,000,000 random coordinates into each of
`points`. the four tables.
