This fixes the following error when trying to upgrade:
```
cannot change name of input parameter "organization_name"
```
The problem was introduced ages ago. I fixed it by running a script:
```bash
BAD_REGEXP='CREATE OR REPLACE FUNCTION cdb_dataservices_client\._cdb_geocode_admin0_polygon (username text, orgname text, country_name text)'
REPLACEMENT='CREATE OR REPLACE FUNCTION cdb_dataservices_client._cdb_geocode_admin0_polygon (username text, organization_name text, country_name text)'
git grep -l "$BAD_REGEXP" | xargs sed -i "s/$BAD_REGEXP/$REPLACEMENT/g"
```
