Supavisor Postgres Connection Pooler on Ubuntu 24.04 LTS
Azure
Databases
Supavisor, a scalable, cloud native Postgres connection pooler with transaction and session modes and a multi tenant model.
Overview
Supavisor is Supabase's cloud native Postgres connection pooler, built to absorb very large numbers of client connections and multiplex them onto a small, stateful pool of native PostgreSQL connections. It supports transaction and session pooling modes, a multi tenant model where each tenant maps to an upstream database, and a Prometheus metrics endpoint for observability. As a PgBouncer class pooler it is a drop in way to protect a PostgreSQL server from connection storms coming from serverless and high concurrency applications.
Why the cloudimg image
cloudimg ships Supavisor secure by default in front of a bundled local PostgreSQL, with one demo tenant wired up so a pooled query works the moment it boots. PostgreSQL and the management API listen on the loopback interface only; the pooler port is the single public surface and the per tenant credential gates access. Every secret, the database passwords and Supavisor's own encryption and signing keys, is generated uniquely on first boot and stored in a root only file, never baked into the image. Paired with a step by step deploy guide and backed by 24/7 support.
Common uses
- Pool serverless and high concurrency client connections onto a small native PostgreSQL pool
- A drop in transaction or session mode pooler in front of a PostgreSQL server
