No, PostgreSQL does not support the WITH clause.  I wanted to use the WITH
clause in an assignment, but I ended up using a view.  Maybe that will
work for you.

Postgres doesn't currently support that. Someone was working on it a while
back, but I haven't heard anything lately, so I don't know if some version
of it is going to be in the next release.

Andrew Overholt was working on it awhile back.  I've been meaning to
pick up the pieces and see what I could do with it, but at this point
it's a pretty safe bet that it won't make 7.5.  Maybe next time.
