ok, i started to review this one...
what the patch is doing seems very obvious and doesn't break the
original logic AFAIUI (i could be wrong, this seems like chinese to me
;)
i made some tests archiving wal and recovering... crashing the server
and restarting... every test was running the regression tests,
don't know what else to do, ideas?
i haven't made any performance tests but it should gain something :),
maybe someone can make those tests?
if not, i will mark the patch as ready for committer some time in the
next hours...
