the same connection will be reused multiple times in the pool

I understand that. As far as I know each datastore operation acquires and then returns connection to the pool. So my logic is the following: QueryRelationships doesn't use cache, so whenever

sum(spicedb_datastore_query_latency_count{operation="QueryRelationships"})

is incremented -> we actually issued datastore query -> we acquired and then returned connection from/to the pool. so I assume the above sum should be equal to (or at least be close to, taking into account other db operation)

sum(pgxpool_acquire_count)

. but with my local docker-compose installation I get like x3.3 difference (with

sum(pgxpool_acquire_count)

being smaller).
