In many GIS workflows, there is a typical scenario where subsets of a PostGIS table must be deployed to external users in a filesystem format (most typically, shapefiles or a spatialite database). Often, there is also the reverse process, where datasets received from different users have to be uploaded to the PostGIS database.
In this recipe, we will simulate both of these data flows. You will first create the data flow for processing the shapefiles out of PostGIS, and then the reverse data flow for uploading the shapefiles.
You will do it using the power of bash scripting and the ogr2ogr command.
