Support for INSERT ... RETURNING

Supprt for INSERT … RETURNING could improve existing API. (http://www.postgresql.org/docs/8.4/static/sql-insert.html) Maybe passing argument to Query end event callback will be good approach?

query.on('end', function(row) {
   if(row) {
      // RETURNING uesd
   }
   else {
     // standard end event
   }
});

RETURNING works. It triggers a “row” event just fine.

If you want to use event listeners, then do this:

query.on('row', function (row) {
  // do some stuff
})

Currently the result does not automatically accumulate rows unless you use a callback. If you want to accumulate rows using event listeners, you have to do this:

query.on('row', function (row, result) {
  result.addRow(row);
});
query.on('end', function (result) {
  if (result.rowCount > 0) {
    // RETURNING used
    doSomething(result.rows[0]);
  } else {
    // standard end event
  }
});

This issue could be closed.
