do you have a distributed server deployment? If so, perhaps the drivers are missing on one of the nodes.
Also, from your screenprint, it appears that it may be a Microsoft driver. But it's hard to tell, maybe it's just because it runs on Windows.
And if you are running a report against the internal postgres, make sure to enable access via "tabadmin dbpass". tabadmin commands
Yes, we have got distributed environment with 2 nodes. 1 Primary and 1 Worker Node.
Access to the PostgreSQL database is already enabled.
The Servers have got 64-bit operating systems and our Tableau Server application is also 64-bit.
The ODBC drivers installed in Primary Node;
The ODBC drivers installed in Worker Node;
Thanks for your help.
the primary node looks out of sync as the Postgres driver should be installed and usually is bundled in with the install of TS. Did you somehow delete it? Can you install the driver manually?
