Ability to specify columsn returned form join

[jdalrymple]

Something similar to this:

{
   type: 'select',
      table: 'mytable',
      joins: [
        {
          target: 'mysecondtable',
          type: 'inner',
          on: { id: '$mytable.id$' },
          columns: '*'
        },
      ],
 }

Which would result in

select "mytable".*, mysecondtable.* from "mytable" inner join "mysecondtable" on "mysecondtable"."id" = "id"."attribute_id"

How about like this:
{ type: 'select', table: 'mytable', columns: ['*', 'mysecondtable.*'], joins: [ { target: 'mysecondtable', type: 'inner', on: { id: '$mytable.id$' } } ] };
?
