PostgreSQL

Purpose

Operate PostgreSQL well: understand what MVCC costs you, why the table is bloated, why the connection count matters more than you think, and how to change a large table without locking it.

When to Use

• Designing schemas or indexes for Postgres.
• Diagnosing bloat, slow queries, or lock contention.
• Configuring connection pooling and replication.
• Running a migration on a large table without downtime.
