I think you're describing a multi-tenant setup, not quite a sharding setup in it's intended use case. Sharding tends to split a single database into multiple databases that contain parts of the whole dataset and all the tenants are interested in querying all of the dataset; sharding effectively just decreases the load on the hardware and allows to support more queries. In your case I believe you'd be better served by configuring multiple databases, e.g.
psql -d tenant1 -c 'SELECT * FROM data LIMIT 1'
psql -d tenant2 -c 'SELECT * FROM data LIMIT 1'
where tenant1
and tenant2
are different databases and consequently tenants in your system.
PgCat doesn't support multiple databases yet, but that support is on the roadmap.
