comment Using ESRI geoprocessing services from a non-ESRI client (Python)?
To send a post request to an ESRI geocoder service, I am using the Python Requests module like this: r = requests.post(geocoderUri, params={"addresses":payload, "f":"json", "outSR":4326}) The payload var contains the json object that encodes the address data in the format that the service is expecting.

comment Do ArcGIS clients that direct-connect to postgresql/postgis databases override configuration settings?
Is the ESRI tool accessing the database as a user that even has rights to do that?

I think the trick is that there is no magic solution that fits all point sets. The computer doesn't know what you want it to look like in the end. st_concave_hull starts with a convex hull and then 'shrink wraps' it based on your value for target percent. I would increase the value of your target percent.

Can you provide an example or define what you mean by complex points? Multi-point features? I am pretty sure that the query that I provided will correctly solve the problem that you diagrammed.

If you are looking for a good PostGIS book, the new PostGIS Cookbook from PACKT is very good.

comment GeoJson to ESRI Shapefile using ogr2ogr
The --version switch didn't yet exist in the version of ogr2ogr that was distributed with FWTools 2.0.6 I am also guessing that it didn't yet support GeoJSON either. 2.0.6 is really old (~2006), is there a reason that you can't use a modern version of GDAL?

comment Reading shapefile tolerance in python
For the non-esri-geodatabase feature classes, they default to the equivalent of 0.1mm in the units of the coordinate system of the data (or 1mm depending on the source you read). For a meter-based system like UTM, it would be .001 meters. Again, this is an esri software thing, it is not an attribute of the data set that is stored in a shapefile.
