as *args, interpreted by the Postgresql dialect as DISTINCT ON (<expr>). [ticket:1069] - select.distinct() now accepts column expressions as *args, interpreted by the Postgresql dialect as DISTINCT ON (<expr>). Note this was already available via passing a list to the `distinct` keyword argument to select(). [ticket:1069] - select.prefix_with() accepts multiple expressions (i.e. *expr), 'prefix' keyword argument to select() accepts a list or tuple. - Passing a string to the `distinct` keyword argument of `select()` for the purpose of emitting special MySQL keywords (DISTINCTROW etc.) is deprecated - use `prefix_with()` for this. - put kw arguments to select() in order - restore docs for _SelectBase, renamed from _SelectBaseMixin
