Odyssey is a production-ready, multi-threaded PostgreSQL connection pooler and request router written in C, built on a custom coroutine engine. It supports transactional and session pooling, per-database/user pool rules, TLS, PAM/LDAP authentication, load balancing across multiple PostgreSQL hosts, and zero-downtime online restarts.

Use cases

• pool postgresql connections for high-traffic applications
• reduce postgres connection overhead under many concurrent clients
• load balance queries across multiple postgres replicas
• route read-only and read-write traffic to primary or standby
• protect against stale reads from lagging replicas
• restart or upgrade the pooler without downtime
• export pooler metrics to prometheus

When to choose

• you need a scalable, multi-threaded alternative to pgbouncer for large production setups
• you want per-database and per-user pooling, authentication, and limit rules
• you need transparent load balancing and target_session_attrs routing across postgres clusters
• you require zero-downtime online restarts of the pooler

When to avoid

• your applications rely on session-level features like temporary tables or session variables with transaction pooling
• you need a pooler that runs on platforms other than Linux or macOS
• you want a simple single-node setup where pgbouncer's simplicity suffices
• you need first-class Windows support
