Hi Evgen,

I just keep pinging this patch thread every once in a while to make sure it doesn't get forgotten :)

How is the syncing with 8.1 CVS coming along?

Hi hackers!

I have done initial implementation of SQL99 WITH clause (attached).
It's now only for v7.3.4 and haven't a lot of checks and restrictions.
It can execute only simple WITH queries like
WITH tree AS (SELECT id,pnt,name,1::int AS level FROM t WHERE id=0
UNION SELECT t.id,t.pnt,t.name,tree.level+1 FROM t JOIN tree ON
tree.id=t.pnt ) SELECT * FROM tree;
It would be great if someone with knowledge of Pg internals can make a
kind of code review and make some advices how to better implement all
this.

Regards, Evgen.
