Recursive Selects

Hello All,
 I wanted to know whether recursive selects are supported in the latest version
 of postgres. I checked out the unimplemented sql constructs and came to know
 that "with recursive" is supported in 7.3, but i could not find any documentation
 for it.
 Actually I have a DB containing the adjancency list (ie tuples of type node1 node2 where
 the graph has an edge between node1 and node2) for a graph. Now given any node
 i need to find out all its neighbours till a depth of say 5. Hence i need a
 recursive select (to avoid giving individual selects as it might take longer
 and i am concerned about speed).
 Sorry if this is a repost, but i could not find much info in the archieves.
 Any help would be appreciated.
 TIA

No.  Some folks at Red Hat worked on it, but didn't finish in time for
7.4.  It might show up in 7.5.
