Can we get SQL Server-like cross database queries

You can reference any table in any database on the same server you’re on as database.schema.table.

With Postgres, it is necessary to set up a FDW connection between every database where you want to perform a query and the database you want to query. In an analytics environment where a single server might have a hundred or so smaller databases, this is a grossly inefficient proposition.

Is it practical to provide the SQL Server-like feature in Postgres?
