The core team has agreed that the data-corruption bug fixed here
http://archives.postgresql.org/pgsql-committers/2010-05/msg00016.php
is serious enough to justify a prompt update release. Although that
bug only affects 8.4 and HEAD, we have some other significant bug fixes
pending in the older back branches, so we may as well do them all.
The current plan is to wrap next Thursday, 5/13, for public release
Monday 5/17. It will probably be appropriate to wrap a 9.0beta2
at the same time.
