The query is derived from a view. I want to select only one column from a
view with many columns. I figured the optimizer would be smart enough in
this case not to join all of the tables needed for the columns I wasn't
referencing at all.

I thought it might be that postgres couldn't optimize the query due to the
fact that it was a view, so that's why I pulled out this portion to see if
it would speed up. But it didn't.
