Slony 1.2.21 should be be fine with 8.4 and can be considered a 
supported version of postgresql.  I'm not aware of any current issues 
with slony and 8.4 but if you hit anything then you should bring it to 
our attention so we can look into it.  It should also work with 9.0 but 
we haven't done much testing of this combination (changes to get slony 
to compile against 9.0 are included in .21)

I've done a fair amount of testing against 2.0.4 and 9.0.  As long as 
your using 9.0 beta2 or above it seems to work okay (so far).  There was 
a Pg bug in beta1 that slony would sometimes hit but this has been fixed 
with beta2.  Strictly speaking 9.0 is still unsupported because it 
hasn't been released.
