i think carlos is confused about master-slave vs multi-master.
carlos,
master-slave async is much easier than multi-master async. yes, pgreplicator
can in theory do multi-master async in a restricted sort of way (the
generalized multi-master async problem is fairly intractable), but you're
right in that pgreplicator is not maintained anymore (and moreover it depends
on a no-longer-maintained dialect of tcl.) if i had infinite time and energy,
i'd be working on a reimplementation of pgreplicator in C, but i don't have
either and i don't see anyone offering to pay me to do it, so it'll stay on
the list of wanna-do projects for the time being.
