Hi all,
as far as i looked around about the new feature: index-only scan, i guess this feature will not include the option such as ms-sql INCLUDE.
For those of us who don't know MS-SQL, can you give a quick explanation of what the INCLUDE keyword in an index definition is expected to do, or some documentation references? It's possible to guess it somewhat from your description, but it's helpful to be specific when asking a question about features from another DBMS.
