That hasn't been the way we've done things in the past. We're frequently
incremental. New features sometimes take several releases to mature.
Taking an example from close by, this will be the third release with
Json, and it's got a bunch of spiffy new stuff, but there's at least one
more round to go (what Merlin calls Manipulation functions), which I'm
rather hopeing someone other than me will see fit to implement.

As for what Peter suggests, I just can't bring myself to do anything
that would require people to say "Oh, you want jsonb? You have to load
hstore." It would be plain embarrassing.
