A conservative approach is never to use version x.0 of *anything*.  The 
PG developers are very talented (and also very helpful on these mailing 
lists - thanks for that), but they are human.  For work I'm paid to do 
(as opposed to my own or charity work), I like to stay at least one 
point release behind the bleeding edge.
