Central2pg : PostgreSQL set of functions to get data from Central

Hi @ridho and welcome to the ODK community. When you get a chance please introduce yourself here.
Thank you for your comment :blush:

Those functions are useful to get ODK data in an external database. So you have to run it in this destination database.

I understand your confusion because Central uses its own database wich is not exposed to the world and does not stores the data in a relationnal way.
