Error connecting Postgres with Gateway
I can connect Power BI Desktop to a local Postgres server, so I published a Power BI report and tried to set up a connection on Power BI Cloud with my local gateway that can access Postgres.
If I try to update the semantic model, I receive this error:

I've installed Npgsql version 4.0.16.0 as stated in the error log and restarted the gateway, but I still get the same error.
My gateway is okay because I use it to access Excel files that are on the local network in other Power BI reports.
Sorry if my English is not correct.
Hi,rinogattuso .Merry Christmas to you.
I subsequently configured the relevant pbix reports according to the official documentation and successfully completed the refresh operation on Service
I hope you find the following test helpful.My servername: localhost:5432
I use the version :PostgreSQL 17There was a problem at the beginning.
Requires version 4.0.10 or earlier (do not download newer versions)Release Npgsql v4.0.10 · npgsql/npgsql · GitHub
Note that you must check the box for
After successful installation restart the computer (you have to restart the computer)
Log in to the power bi service and configure the on process gateway.
When the gateway is set up correctly, the data source credentials issue is automatically resolved as well
PostgreSQL Refresh Successful.
I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.

Gateway install files do not include the Postgres drivers. You can borrow them from the Desktop install.
From C:\Program Files\Microsoft Power BI Desktop\bin\ADO.NET Providers
to C:\Program Files\On-premises data gateway\m\ADO.NET Providers
everything npgsql
Hi,lbendlin,thanks for your concern about this issue.
Your answer is excellent!
And I would like to share some additional solutions below.Hello,rinogattuso .I am gald to help you.
I found the relevant issue link from my browser, hope it helps.

And I've noticed that some users try to use the ODBC connector instead of the PostgreSQL connector, but be aware that you'll need to reconfigure the data source and may need to modify the query.

If you need to use a gateway to connect to PostgreSQL, using ODBC is also a good idea.
Using ODBC is also a suggestion to try.
