Sorry, let me clarify. I used Postgres to generate the counters as external IDs into other data stores (so instead of `give me a new uuid` I said `hey postgres give me a new counter`. Postgres was only used to maintain the counters themselves in a tiny database where compression isn't relevant anyways. The other data stores where I used this were a combination of Parquet on S3 (where you get compression) and ScyllaDB (where you also get compression).
