- 7Hacker News·7/11/2026researchPgBouncer fleet scales Postgres pooling to 4x throughput
ClickHouse Managed Postgres describes running multiple PgBouncer processes behind one endpoint using so_reuseport and peering to spread connection pooling across CPU cores. In identical EC2 tests, the multi-process setup reached about 4x the throughput of a single PgBouncer process while preserving query cancellation and connection limits.

PgDog, a proxy for scaling Postgres, introduces connection pooling designed to reduce the usual trade-offs of poolers like PgBouncer and RDS Proxy. It can detect and replay SET state, and it also supports LISTEN/NOTIFY across clients and multiple PgDog processes while preserving Postgres semantics.
