So, share it. I'd look forward to hearing it, especially since your
vision probably takes synch rep and quorum commit into account, which
mine doesn't. If not here, then on your blog.

*shrug*. Robert asked me to write it up for the list based on the
discussions around synch rep. Now you're going to bash me for doing so?
Many of the goals I described will mean removing knobs and changing
defaults, or even foregoing fine-grained control entirely. If we don't
have agreement that simplifying replication is a high-priority goal,
then it won't happen; anyone submitting a patch will be
this-or-that-use-cased to death and will give up.
For that matter, I'm not sure that everyone agrees that simplification
is a worthwhile goal. For example, somewhere between 9.0beta4 and final
release, someone changed the defaults for max_wal_senders and
hot_standby to "0" and "off". I don't remember there even being
discussion about it.
The discussion around synch rep certainly showed that the "natural"
tendency of this list is to add complexity with each incarnation of a
feature. It's the easiest way to accomodate conflicting use cases, but
it's not the best way.
