My question is when I don't use the Recursive term does the optimizer just
consider it as a subquery or does it work like Oracle's WITH CLAUSE
(Subquery Factoring) ? Oracle's WITH CLAUSE boosts the performance of the
queries. So does this do the same?
See the fine manual, for instance last para here:
http://developer.postgresql.org/pgdocs/postgres/queries-with.html
Cool :)
From http://umitanuki.net/pgsql/wfv08/design.html I got the impression that
windowing functions will make into (at least partially) into 8.4 because on that
page several items are marked with [DONE].
I can't see anything in the developer docs regarding them. Does that mean they
won't make it or that simply the documentation isnt't yet there?
Cheers
