PostgreSQL data source - connector is not configured correctly.

This is insane Microsoft. Pay the man to make an install that connects his software to Power BI handling ALL problems. PostgreSQL is the 4th most widely used database. You need to make this seemless Microsoft. Someone already went to the trouble of doing most of the hard connectivity work for free. You need to fund him to deal with the PITA nonsense part that is the difference between Power BI being The GoTo BI product for PostgreSQL, and what it currently is (only used by gluttons for punishment or the lucky who happened to have all the right combination of software versions that make it magically work).
