Hm, you're right:
http://www.postgresql.org/devel-corner/docs/postgres/xact-read-committed.htm

"Read Committed is the default isolation level in Postgres. When
a transaction runs on this isolation level, a SELECT query sees only
data committed before the transaction began..."    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Must be "committed before the *query* began" as it was in 6.5 docs.
Any way to fix it before release?
