PostgreSQL connection through On-premise Data Gateway

Hi everyone,

I need to connect my app.powerbi.com to a PostgreSQL database. I have an on-premise data gateway installed on my computer (the computer where I have my PowerBI Desktop and my report design, etc.).

The issue is that when I try to set the PostgreSQL origin in the Gateway Configuration in app.powerbi.com, the specific option for this database doesn't exist.

Could I set the PostgreSQL origin through another origin (i.e. SQL Server or MySQL) ? If this is not possible, which is the alternative?

Thanks a lot,
Kind regards.

    Hello,

    for ODBC connection to postgres you need to get installed ODBC driver for postgres;i am using PostgresSQL Unicode(x64).

    After that you have 2 options:

    1) create user DSN via ODBC data source administrator (C:\Windows\System32\odbcad32.exe). In that case the connection string for ODBC data source is "dsn=dsn_name" where dsn_name represents the user dsn created via tool above

    2) alternative option for connection string is: driver={PostgreSQL Unicode(x64)};server=server_name;port=5432;database=db_name

    where server_name represents a server name or its IP, db_name is name of database.

    For using on-premise gateway you need to use ODBC connection to postgress on power bi desktop. Then you need to configure data sources using ODBC the same way on on-premise gateway.

     

    I am using above approach for connection to multiple different postgres databases.

    I hope it helps.

     

    Kind regards

    Hi,

    you need to use ODBC. ODBC must be used also on power bi desktop to ensure that data sources would match.

      Hello,


      Thanks for your reply.


      I'm not finding anything about how to do that in the Documentation, could you give some advice? For example, I don't know how to build the "connection string" for the ODBC connection.

       

      Thank you,
      Kind regards.
