   @cgivre, in your previous comment, you have mentioned that when plugin 
itself handled projection pushdown, this issue wasn't observed, so I assumed 
that it wasn't done by EVF (at least in this case).
   
   Regarding user experience, I doubt that it would be better for user 
experience to introduce this config option, it just confuses the user: `SELECT 
*` should return all the records, but it will ignore specific column. What 
behavior is expected if the user would specify this column explicitly, or if he 
would add a filter with this column, or even aggregation?
