Is there a complete list of currently known pg2 bugs published someplace
(besides this email thread), perhaps with suggested work arounds until a
new pg2 can be released?

In my case hot loading of all modules which contain client code performing
pg2 lookups is an option, so I have a chance to avoid disaster (as
described by Matthew above) if I act fast :-)
