The talk is that the tsearch2 contrib module will be redone to access the
built-in functions for 8.3. If this is done, backwards compatability should
be pretty easy to work out. Help in that area would be greatly appreciated
(and it may not get done if no one offers to help)
That said, I think it is in a DBA's best interest to migrate to the built in
stuff asap. From what I've seen most of the data types are easily compatible,
the biggest problem is removing the cruft from your schema dumps for doing
the upgrade. Not that much different than going from 8.1 -> 8.2, which I have
blogged about previously. HTH.
