| One of the few really useful features of SQL Server that Postgres doesn’t have is straightforward 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? |
