Subqueries in from clause

It looks like if subqueries in from clause are not supported by
PostgreSQL. Am I right ? If yes, are there any plans to provide this
feature soon ?

I would like to use Postgres for teaching SQL as a replacement for a
well known commercial product which I find too heavy, too not open
source, too everything ! For this kind of usage I need most SQL92
features, at least for query expression.

Thanks for any information or advice about this topics.
