I just saw this in the pgsql-hackers list:
From: The Hermit Hacker
Subject: [HACKERS] RC2 scheduled for Tomorrow
evening...
To:pgsql-hackers@postgresql.org
Just a heads up for anyone that might have something outstanding ...
I'm going to package her early evening (~18:30AST) and announce it to
both pgsql-hackers and pgsql-announce when done...
Once RC2 goes out, its meant to be a "this is what we'd release if
docs were completely ready to go" ...
Which means that tomorrow's release is the final release, with some
missing corrections to the docs. No need to wait anylonger :)
