What is intended for PostgreSQL is decidedly NOT the "Oracle syntax"
(which more or less predetermines a special case of recursion), but
rather the "WITH [definition] select [which can reference
[definition]]" approach seen both in DB2 and the SQL 2003 standard.

There have been a couple of abortive starts to this; I seem to recall
someone having offered to work on it in the 8.4 branch.
