Comment (by ikelly):
The current patch also doesn't work with Oracle, which doesn't support the
"DISTINCT ON" syntax and requires an analytic query for this purpose. I
tried coding that up some time ago, but I found that the query
architecture didn't really lend itself well to using analytic functions.
That was before the sql compiler refactor, so I'll have to give it another
look. It may be easier now.
