I would like to get back into working on autovacuum, outside of
discussions on the lists I haven't done anything since you took it from
contrib. Anyway I am interested in helping if I can find the time but
there is no chance of that happening in the next few weeks, but maybe in
January.
I think another thing to consider are good default values for the
autovacuum vacuum delay settings. We talked about this a while ago, but
I don't think we ever settled on anything.
