postgresql-11-citus - 8.0.0.PGDG-2 main

Citus is a distributed database implemented as a PostgreSQL extension. It
provides functions to easily split a PostgreSQL table into shards to be
placed on remote worker nodes. Citus can replicate shards, update their
schemas, and keep track of shard health. An advanced distributed planner
is included which handles queries and modifications against sharded tables.
