For the "Deprecate MD5 password authentication" item, IMHO we should
emphasize that support for MD5 passwords will be removed in a future major
release, as we did for the 18beta1 announcement. Here's an attempt:
Deprecate MD5 password authentication (Nathan Bossart)
Support for MD5 passwords will be removed in a future major version
release. CREATE ROLE and ALTER ROLE now emit deprecation warnings when
setting MD5 passwords. These warnings can be disabled by setting the
md5_password_warnings parameter to "off".
