PostgREST 12.2: Prometheus metrics

PostgREST 12.2 introduces observability and API improvements, including Prometheus-compatible metrics for the schema cache and connection pool, hoisted function settings allowing custom timeouts per function, and a max-affected preference to limit affected rows up to a custom value. These enhancements improve troubleshooting and provide greater flexibility in managing SQL statements and mutations. The latest version is available on the Supabase platform for new projects or as an upgrade for existing ones.
