My 2 cents to Mu's answer. I'm posting this as an answer cause I don't have enough reputation to add a comment.

JSON is becoming the go-to solution for storing "complex" data.

Oleg Bartunov--one of the authors of hstore--himself stated that there is no advantage using hstore over JSON and he encourages people use jsonb.

On Mar 23, 2014 jsonb, a structured format for storing json, was formally introduced in the pgsql development mailing list.

On May 15, 2014 JSONB was listed in the PostgreSQL 9.4 Beta 1 release announcement.

JSONB: 9.4 includes the new JSONB "binary JSON" type. This new storage format for document data is higher-performance, and comes with indexing, functions and operators for manipulating JSON data.
