Configure Gateway to connect to PostgreSQL
I'm running into an error when trying to create a new data source on my data gateway:
Cannot connect to the mashup data source. See error details for more information.
PostgreSQL: We were unable to find a database provider with invariant name 'Npgsql'. This error could've been the result of provider-specific client software being required, but missing on this computer. To download client software for this provider, visit the following site and choose the 64-bit (x64) version of, at minimum, 'Npgsql version 2.0.12': https://go.microsoft.com/fwlink/?LinkID=282716
Has anyone ran into this before? Other similar questions seem to be specific to when establishing the connection on Power BI Desktop. The solution there is to download the data provider.
Do I need to install this on the server hosting the data gateway??
2 Things to get this to work:
1. Install the Npgsql provider on the server that's hosting the data gateway (https://www.nuget.org/packages/Npgsql/4.0.2)
2. Reboot the server
Should now be able to use the PostgreSQL data source type when creating the data source in Power BI Service.
vrocca,
As your post, you would need to install Npgsql provider on the gateway machine and make sure that you have access to the postgreSQL data source on the gateway machine.
You can treat Power BI gateway as another client like Power BI Desktop. When using Power BI Desktop to connect to postgreSQL, Npgsql provider should be installed on the Desktop machine, so does the gateway.
