Well, I stand corrected. I thought OP did not know that (given they said they didn't know anything about postgres and were talking about "recompiling all binaries"), but reading their posting history they probably do.

With "doesn't distribute well" by the way I meant that it doesn't distribute well as program binaries, not across a cluster. It used to be extremely common to recompile e.g. your Linux kernel, nowadays almost nobody does that unless there are some very specific needs. Of course, building a specialized postgres cluster for exceptional scale would easily qualify.
