pgbouncer

PgBouncer is a lightweight tool that helps manage connections between applications and a PostgreSQL database. When many users or applications try to access the database simultaneously, it can become overwhelmed, leading to slowdowns or crashes. PgBouncer reduces this load by maintaining a pool of connections, efficiently sharing them among multiple users, and reusing existing connections instead of creating new ones each time. This improves performance, stability, and scalability, especially in high-traffic environments, ensuring that the database remains responsive and available to all users.
