Sentry runs large workloads and Postgres isn't a bottleneck. We have also never employed a DBA. Most users never need to shard their database, and at most can just partition datasets by tables for _extremely_ high volume workloads.
You just have to consider architecture and optimize things that are slow, just like any other software. Nothing is free at the end of the day, and nothing else gives you the flexibility that Postgres does, particularly these days with its growing high value extensions.
