PostgREST 12

PostgREST 12 introduces several major features, including JWT caching, Server Timing Header, support for aggregate functions, and media type handlers. JWT caching significantly improves performance by reducing the time spent decoding tokens on each request. The Server Timing Header provides better visibility into server-side performance by timing various phases of a response. Aggregate functions such as avg, count, max, min, and sum are now supported, allowing for more complex queries. Media type handlers enable custom media types to be handled and override built-in ones, offering flexibility in serving different content types directly from the database.
