I also have another database named geo that is a PostGIS database for storing geopolitical and geospatial data. I want to set up a foreign data wrapper in stp to connect to geo, so that for each address in stp, I only have to store the primary key value of the lowest level geo unit, such as a city. I can always display the city's county, state, country, whatever in views in stp. I plan to have other databases that need geo data so I want a single source of truth for geopolitical and geospatial data. My questions are: 1. Do I have to install PostGIS in stp?....or is it sufficient to install PostGIS only in geo? If you want to use Postgis functions & datatypes in stp you will need Postgis there 2. Do I need the postgis extension in stp? (I'm thinking yes, but I don't want to guess.) Isn't this the same as (1) above? (Postgis is installed via "create extension postgis;") 3. I want to geocode addresses in stp. Do I need to install any geocoding software in stp?...or can it be used from geo? If you can geocode in geo & access the resulting data via fdw in stp, you should not need geocoding tools in stp. If you need to access spatial data from geo in stp & geocode in stp, you will need the geocoding tools in stp. Thanks for your help!
