In web2py, distinct can be boolean (distinct=True) or an expression, as
quoted from the book. Boolean works fine, but expression maps to DISTINCT
ON.

It is in BaseAdapter class, _select method. I think only nosql adapters
override that method.

I think that this is a issue with differents adaptors...

And you maybe right that DISTINCT ON is only available on postgres...
