In what sense are we really stopping hstore development if hstore2
lives as jsonb? I have a hard time imagining someone dealing with the
incompatibility that a user-facing hstore2 would introduce, while
still preferring hstore syntax over json syntax given the choice.
There are very rich facilities for manipulating json available in
every programming language. The same is not true of hstore.
Having looked at the issue today, I think that the amount of redundant
code between a hstore2 in core as jsonb and hstore1 will be
acceptable. The advantages of making a clean-break in having to
support the legacy hstore disk format strengthen the case for doing so
Heh, let's not to do an implusive decision about hstore2. I agree,

in json(b). Also, it'd be a bit awkward after working on nested

I hear you, and largely agree, as long as the compatibility issue is
solved. If it's not, I think inventing a new hstore2 type is probably a
lousy way to go.
For good or ill, the world has pretty much settled on wanting to use
json for lightweight treeish data. That's where we'll get the most
impact. Virtually every programming language (including Perl) has good
support for json.
I'm not sure what the constraints of json that you might want to break
are. Perhaps you'd like to specify.
Whatever we do, rest assured your work won't go to waste.
