Thanks for asking, perhaps our plans weren't public enough. pglogical has
already been announced as open source, under the postgres licence and that
it will be a submission to core PostgreSQL, just as BDR was. pglogical is
in development/test right now and will be released when its ready, which
hopefully will be "soon", aiming for 9.6.

Thanks also for the opportunity to let me ask what your plans are regarding
contributing to core? I couldn't make it to SF recently because of a
funding meeting, but I heard something like your company will release
something as open source sometime in 2016. Could you clarify what that will
be, when it will be, what licence it is under and if it is a contribution
to core also? Is that something you're working on also?

I don't know the status of Konstantin's work, so same question for him also.

It will be useful to help work out what parts need work on once pglogical
is done.

For me, submission to core means both that it is postgres licenced and that
the copyright is novated to PGDG, allowing it to be included within PG core.
