PgBouncer in Debian 13

PgBouncer is a lightweight, command-line–driven connection pooler designed for PostgreSQL databases. It allows organizations to efficiently manage, reuse, and scale database connections without overloading the database server.

Features of PgBouncer:

• CLI-based database connection pooling and management.
• Supports multiple pooling modes: session, transaction, and statement.
• Authentication management with MD5, plain-text, or PAM.
• Logging, monitoring, and metrics for connections and queries.
• Lightweight, high-performance, and scalable for large applications.
• Supports TCP and Unix socket connections, with optional TLS/SSL for secure deployments.

To check if PgBouncer is installed and accessible, use the following steps:
