Using the PostgreSQL Dialect
If you just want to do something simple, you can try connecting directly to the JDBC driver
and using Tableau-provided PostgreSQL dialect.  
1. Create a DuckDB file containing your views and/or data.
2. Launch Tableau
3. Under Connect > To a Server > More… click on “Other Databases (JDBC)” This will bring up the connection dialogue box. For the URL, enter `jdbc:duckdb:/User/username/path/to/database.db`. For the Dialect, choose PostgreSQL. The rest of the fields can be ignored:  
![Tableau PostgreSQL](../images/guides/tableau/tableau-osx-jdbc.png)  
However, functionality will be missing such as `median` and `percentile` aggregate functions.
To make the data source connection more compatible with the PostgreSQL dialect,
please use the DuckDB taco connector as described below.
