Citus
Shares rank 8 of 14 Postgres extensions by recommenders
Open-source Postgres extension for sharding and scaling out across nodes, praised for maturity and a strong query engine. Critics say one coordinator node fans out requests and that it is not fully feature-complete.

Scales out through sharding and query routers
“So with Citus you can absolutely have as many query routers (coordinators if you wish) as you want.”
Comment from 11 Jun 2026 in “PgDog is funded and coming to a database near you” “get sharding by schema for free, so you have both isolation and more or less infinite growth”
Comment from 5 Feb 2026 in “Don't rent the cloud, own instead” “Shard rebalancing is fully built-into Citus as a UDF”
Comment from 11 Sep 2026 in “Neki – Sharded Postgres” Proven and mature for critical workloads
“It is a brilliant piece of technology that supported mission critical workloads”
Comment from 12 Sep 2026 in “118M Queries per Second on Neki” “Feature-full, proven, mature, boring.”
Comment from 11 Sep 2026 in “118M Queries per Second on Neki” Advanced query engine for large aggregations
