After reading this SO question
<http://stackoverflow.com/questions/25263736/jsonb-with-psycopg2-realdictcursor>
I'm thinking that users expect jsonb to work exactly like json does.
Our docs say that json is automatically converted into python objects
since psycopg 2.5
<http://initd.org/psycopg/docs/extras.html#json-adaptation> so I think
we won't get many complaints if starting from 2.5.4 we supported jsonb
the same way. Only behavioural change would be noticed by users
running an older psycopg2 version with a still-to-be-released Postgres
version, which is an odd combination at best, unlikely to be found in
the wild. it would be a better scenario if people upgrading their
schemas from json to jsonb found their default psycopg installation
not changing behaviour with the different data type.

So, if nobody shouts in disagreement, there will be a 2.5.4 released
in a few days/couple of weeks with a handful of secondary bugfixes and
jsonb support baked in.
