Move DPA from MSSQL to PostgreSQL

Hallo, we already have a DPA server that use MSSQL on the same server, we want start using postgresql on a separate server, we do not need to move the previous data, so we can start with an empty DB. I have some doubts, I create an empty db, an user in order to allow dpa to connect to postgresql and insert new port and address in DPA db settings, but the db structure? The first time DPA connects to the new db will create and populate the db automatically?

Where can I find a step-by-step guide for my situation?

Thanks, Pietro.
