Is it the hierarchical query ability you're looking for or pivot?
The former we are actually getting in 8.4.
AFAIK even in systems with pivot you still have to
declare a fixed list of columns in advance anyways.
Do you see a system where it works differently?
MS-Access SQL has a TRANSFORM clause that allows for crosstab queries
without the need to know in advance the number of columns:

As for Oracle, it wasn't possible until recently but now 11g has the
PIVOT clause:

In contrast of these clauses, PG's contrib/tablefunc looks more limited
and quite harder to use.
