No, Bruce didn't like the way I did certain things, and had some qualms
about the value of supporting multiple wire protocols IIRC. Plus the
patch was not really ready for primetime yet.
I'm hoping to get back to it soon and sync it with the latest CVS, and
clean up the odds and ends.

Not really, there is some ongoing standards activity adding some new
features. The list of supported types is pretty impressive, anything in
particular you are looking for?

I don't know the answer to this. The spec is pretty huge, so it may, but
I haven't seen it.
Even if it is supported as a secondary protocol, I believe there is alot
of value in having a single database protocol standard. (why else would I
be doing it!). I'm also looking into what it will take to do the same for
MySQL and Firebird. Hopefully they will be receptive to the idea as well.
