First, I want to apologize for not completing the release notes earlier
so that others could review them. I started working on the release
notes on Friday, but my unfamiliarity with the process and fear of
making a mistake caused many delays. I have improved the documentation
on the process which will hopefully help next time.
Second, I have read the thread beind this patch:
http://www.postgresql.org/message-id/flat/51798552.2010...@vmware.com#51798552.2010...@vmware.com
You are right that there is alot of details skipped in the release note
text. I have developed the attached patch which I think does a better
job. Is it OK?
