Description:

We're trying to use Cube as our OLAP backend for our PowerBI reports. Cube
make use of Postgres as a backing database. Currently we're using SQL Server
to connect our reports using Tabular Object Model. 

Can you please advise if it is possible to connect to a Postgres database
using Tabular Object Model and if so, what is the format to do that?

We have been unable to to use a postgress connection string through ssas to
use the tabular object model.
