### Preps the db table, reads address data, builds a request url, returns lat/long/precision valuse to the same table, | |
### transforms coordinates to 4326 then 2232. | |

## Script for building spatial indexes on tables that do not have them already. | |
## Attempts to build spatial indexes for all geometry fields in the db. | |
## | |
## Uses the PyGreSQL module | |
## | |
## Future Improvements: | |
#### add some handling of existing indexes to possibly delete them and rebuild them with this naming convention | |
#### rather than just building a list of tables that have 1 or more indexes this should determine what fields for a specific table have an index (or dont) and handle them. | |
###### The current script would not catch a second geometry field in a table that has a single index because it would not be added to the index_list. |
