Summary
A survival guide for Postgres provides strategies to prevent system failures based on two years of practical experience. The guide aims to offer concise, actionable insights for engineers facing Postgres challenges.
Key Takeaways
- The guide emphasizes the importance of writing a good schema, suggesting iterative development based on application needs and common query patterns.
- It recommends using identity columns or UUIDs for primary keys, always employing primary keys, and utilizing foreign keys with cascading deletes for low-volume tables.
- Efficient read queries in Postgres rely on using explicit indexes, unique constraints, or primary keys to avoid slow sequential scans.
- The guide highlights the significance of understanding the query planner and autovacuum processes for optimizing Postgres performance.

Positives
- Using pgbackrest for point-in-time recovery has proven to be a game-changer, making backup processes smoother and more reliable than previous custom solutions.
- Running Postgres on a $10 VPS is a viable option for many, especially when you're bootstrapping and want to save costs without sacrificing functionality.
- The advice on deterministic lock ordering is gold — it could save developers from deadlocks, which is crucial for maintaining app performance.
Concerns
- Many commenters express that Postgres can become prohibitively expensive for solo founders trying to bootstrap, especially when free-tier alternatives seem more viable.
- Relying on cascading deletes is seen as risky and 'magic' by some, highlighting the confusion it can cause for developers who primarily work outside of the database realm.
