My slony 1.2.21 README says nothing of the sort.

My INSTALL document, which has a datestamp of 2007-08-28 23:44 says it
has changes to support features expected in 8.3.  Which means this
file hasn't been updated since before 8.3 went official relase.

Computer says no.

time to look for more up to date docs.  Go to the front page of slony,
click on the link on the right that says:
http://main.slony.info/downloads/1.2/source/slony1-1.2.21-docs.tar.bz2
and get a 404!  Woohoo.  Copy and paste that url, changing 21 to 20,
and viola, I get a download.

installation.html specifically mentions 8.3 and 8.4 and seem to imply
they're supports.

I'm pretty sure it is considered supported.  It certainly works well
in my 8.3 cluster and has for two years straight, with bug fixes
against slony 1.2.x against all versions up to 8.4 being supported.

I wonder if it will be considered supported for 9.0.?
