POSTGRESQL
PostgreSQL is the most widely used open-source engine on new critical platforms. The most common production issues are bloat from a misconfigured autovacuum, lagging replication (streaming or logical), major version migrations, and Patroni-based high-availability architectures. These guides cover those scenarios with real commands and validations, not just theory.
