maybe just "initial database setup verification", not necessary only cluster
| - Infrastructure performance testing | ||
| - Database configuration validation | ||

Since you are writing the README, it makes sense to describe the light/medium/heavy tables before you describe Insert/Update
Also the tenants table and the idea of the tenant-aware operations
| - `--workers`: Controls the number of concurrent workers for parallel operations | ||
| - `--chunk`: Controls the number of loops for insert and update operations | ||

| ## Reference Results |

I would move the results to separate file not to polute README... because I'd expect a lot of combinations of results. Maybe it would make sense to have:
results/test.sh << here you just put all the command lines you executed
results/macbook-pro-m1.md << the results themesleves
results/macbook-pro-m4.md

1G could be not enough, especially for servers, I'd use at least 8G not to get it cached by RAID caches

I have tested with 32G, it showed even more huge difference in performance between MacBook PRO and prod-like server

ERR means your DB is misconfigured, it's better to have OK everywhere
Especially in case of PostgreSQL

The same issue - there must be no ERR - the results could be impacted by these settings with ERR's
