Could I request that a link to the developer docs be posted along with
the release docs on
http://www.postgresql.org/docs/manuals/
?
First -- it is interesting. Second, if one is running CVS HEAD for
testing (always a service to the community, if not your data), they
are the appropriate docs. Finally, it gives users a chance to see why
they might want to upgrade (for example by browsing the awesome
windowing capabilities, etc).
And yes, I could write a patch,...
