I wouldn't pin all my hopes on a project still under development. (For
me, personally, add the fact that Slony-I still has not solved
single-master replication in a way that doesn't burden the
developer/DBA with lots of unnecessary extra maintenance; I am not
counting on its developers to fix this issue in Slony-II.)
In the meantime, Cybertec (http://www.postgresql.at/, an Austrian
company) just announced a commercial synchronous multimaster
replication product based on 2-phase commit. It's expensive, and I
can't speak for its maturity, and it may or may not scale as well as
the projected Slony-II design, but the setup seems dead simple, and
from the docs I have found it seems to transparently replicate schema
changes, unlike Slony-I. So that's something.
Alexander.
