Expand description

Rewrite rule for adding alias to duplicated projection

This rule is to deal with sql like SELECT n.oid, n.* FROM n, which is a valid statement in postgres. But datafusion treat it as illegal because of duplicated column oid in projection.

This rule will add alias to column, when there is a wildcard found in projection.
