Postgres with QUIC: Why Stream Multiplexing Beats Traditional TCP Connection Pooling
- Every backend engineer running Postgres at scale eventually learns the same painful lesson: connection pooling does not fix network physics.
- We deploy PgBouncer or PgCat, configure transaction pooling, lock down backend connections so the database doesn't run out of memory, and celebrate.
- But if your application or edge services sit tens of milliseconds away from your database cluster, your queries are still choking on a transport bottleneck we rarely talk about: the client-side TCP connection pool.
