Ok, it seems I was totally wrong with the work_mem setting. I'll
adjust it to a more saner level. Thanks a lot for the advice everyone!

It shows all the operators, but it doesn't really say that these
all will actually run in parallel right? Of course I guess it would
give a good idea about what the upper bound is.
You can determine what runs in parellel based on the indentation of
the output. Items at the same indentation level under the same
"parent" line will run in parallel
