That&#x27;s not quite correct. The jsonb requires that reads deserialize jsonb into textual JSON, whereas the json type can be sent directly to the client with no processing.<p>jsonb is superior when:<p>1. You want to use any of the built-in JSON functions, e.g. for extracting fields from the document.<p>2. You want to index the JSON (either the entire thing via GIN, or individual fields via ordinary B-tree indexes).<p>3. You want to save space; jsonb strips whitespace.<p>jsonb incurs an overhead on both reads and writes since it must serialize to&#x2F;from textual JSON.
