PostgreSQL JSONB: A Complete Guide to Storing and Querying JSON Data

We just published a deep dive on PostgreSQL JSONB, covering everything from basic storage and querying to GIN indexes, JSON path queries, and real world patterns for production use.

If you're building a SaaS product on PostgreSQL and storing any semi-structured data (user preferences, API responses, event payloads, feature flags), JSONB is one of the most underused tools in the stack. It gives you document store flexibility without leaving your relational database.

The guide covers:

• JSON vs JSONB and when to use each
• Extraction, containment, and existence operators
• GIN indexing for fast lookups on nested keys
• JSON path queries (the SQL/JSON standard way)
• Four real world patterns: user preferences, audit logs, API response caching, feature flags
• Common performance mistakes and how to avoid them
