Hi there,
I guess many - if not most - here have tried
pgcluster. For those who didn't, postgresql is pretty
much the equivalent of pgcluster configured without
load balancer or replicator, in read-write standalone
mode. From a user point of view, that's three maximum
additional configuration files, which can be basically
set to those default values and distributed as is in
standard (making installs/upgrades transparent to
non-cluster environments). From a developer point of
view, the pgcluster code is quite easy to take a hold
on.
pgcluster still has quite a few pending issues, but
it's good enough for many users. Integrating it as
part of a standard postgresql distribution would
likely not disrupt standard postgresql functionning,
while giving it the replication features it lacks as
is. It's also likely to accelerate its maturing by a
more widespread adoption and as a result overcome most
of its issues.
If the idea of its integration in the main postgresql
code is of any interest to the postgresql team, I'm
willing to invest some effort on it.
