This patch has been proposed and rejected before. It doesn't do the
SQL-standard syntax for recursion, and I have little faith in the
implementation even if it did the right syntax.
There has been some work done towards implementing the spec-compatible
syntax, but it's not likely to get finished in time for 7.5 :-(
