Dear administrator,

I would like to know whether PostgreSQL has some help tips (hints) for
query optimizer that can help to use it more efficiently (for instance, as
Oracle has such tips for optimizer as ?hint?)? If it has, so, please,
inform me a version (I know, that 8.3 version has not such features). If
it has not, so will be there such hints in the future version?

Sincerely yours
Anuar
