This describes not only JSON fields/blobs in a traditional RDBMS, but also the impulse that drives much NoSQL adoption. It's just easier to be able to dump whatever you want in there, developers love it, no chatter about normalization and all of that silly DB stuff. This almost invariably comes back to haunt them, often in astonishingly damaging ways. Use schemaless options, including JSONB in PgSQL or doc DBs like Mongo, for data that really needs it due its unpredictable nature, NOT data that you're too lazy to draw out a schema for.
