Working with a PostgreSQL database as a OLE DB destination

Hello:

I am using VS 2019 and trying to move data from SQL Server to PostgreSQL 11.3. When I try to create a OLE DB Destination pointing to a PostgreSQL database using PostgresSQL Ole DB Provider, the initial Catalog is disabled. 

Can someone tell me how I can enable it so I can choose the database table I am interested in?

As you may know, PostgreSQL structure is quite different. It can have multiple databases and each database can have any schemas.

Thank you.
