What is it?
PostgreSQL supports arrays of any type, JSONB for indexed JSON, UUID, range types, and network address types.
Why does it matter?
PostgreSQL's rich types eliminate workarounds. A PHP array column is one field; MySQL requires a separate table.
Learn PostgreSQL-specific types — arrays, hstore, JSONB, UUID, and range types.
