I'm trying to figure out why a sequential scan is out performing. I've tried psql 13.7, psql14.6 and REINDEX. The REINDEX didn't help. This is on an RDS instance that's a db.m5.large (2 * vCPU, 8 GB memory) with 200 storage on io1 with 10000 provisioned IOPS. I restarted the RDS instance in between each test.
