| -- GEOIP IN POSTGRESQL | |
| -- | |
| -- We use two approaches. First using PostgreSQL inet and cidr types and indexing (PostgreSQL 9.4 and later), | |
| -- and then using ip4r (https://github.com/RhodiumToad/ip4r). | |
| -- The performance of ip4r indexes is significantly better than PostgreSQL's own index. | |
| -- An operation that took 42s using ip4r took 47 minutes using PostgreSQL's cidr index. | |
