TOAST (The Oversized-Attribute Storage Technique) in PostgreSQL helps manage large data values exceeding the 8kB page size limit using compression and out-of-line storage. It supports various data types and uses four storage strategies: PLAIN, EXTERNAL, EXTENDED, and MAIN, each with different methods for managing oversized data. Understanding TOAST strategies can help optimize database performance.
