Too many database connections

After moving the API to serverless functions, PostgreSQL starts failing with "too many connections" during traffic spikes. What is the best fix?

A.Open a new database connection inside every request and never close itB.Use a connection pooler such as PgBouncer, RDS Proxy or a provider pooled endpoint, and create the client once outside the handler so warm instances reuse itC.Increase max_connections to 100000D.Switch every query to run inside one long transaction
