🏛️ The 10 Commandments of Principal Database Engineering

1. Explicit Selection: Never ship SELECT * to production.
2. Covering Indexes: Eliminate heap lookups for latency-sensitive queries with covering indexes.
3. Deterministic Locks: Acquire locks in strict primary key order to eradicate deadlocks.
4. Short Transactions: Never hold locks during external network or CPU-heavy calls.
5. Keyset Pagination: Always prefer cursor pagination over high OFFSET values.
6. Universal Parameterization: Defeat SQL injection 100% of the time with prepared statements.
7. Expand & Contract: Make schema migrations non-breaking through parallel rollout.
8. Pool Responsibly: Keep connection pools small and right-sized to CPU cores.
9. Automate Autovacuum: Tune autovacuum to run small and frequent to prevent disk bloat.
10. Test Restorations: Verify continuous WAL archiving and Point-in-Time Recovery regularly.

🚀 Final Words

You now possess the foundational knowledge, architectural wisdom, and operational runbooks to design, optimize, and maintain world-class relational database systems. May your execution plans be clean, your transactions swift, and your uptime 99.999%!
