Comment 12 for bug 1523544

Folks,

First of all we don't use JSONB [1], we use JSON [2] type. As Dmitry T. has pointed, the JSON type was introduced in PostgreSQL 9.2. That means, I see no reason why we need to upgrade PostgreSQL. Let's be as close as possible to distributive package, and do not maintain our own one.

[2] http://docs.sqlalchemy.org/en/latest/dialects/postgresql.html#sqlalchemy.dialects.postgresql.JSON

I believe we should move it to Invalid.
