I'm pretty skeptical that Java's GC could get better performance than
palloc. As for threading, ISTM Java doesn't offer anything we couldn't
get through POSIX threads if we were going to contemplate a full-scale
rewrite anyway (which I think everyone agrees that we aren't).

Are there any advantages that this would provide that we could get
without investing so much effort? For example, PL/Java seems like a
reasonable approach to Java & PG integration that doesn't involve
rewriting hundreds of thousands of lines of code.

P.S. While we're contemplating pies-in-the-sky, I'd personally love to
rewrite PostgreSQL in Objective Caml.
