This guide details essential configuration settings for hardening PostgreSQL security. Learn how to enforce modern authentication using `pg_hba.conf` (SCRAM-SHA-256), implement mandatory SSL/TLS encryption, and minimize the attack surface by restricting network listeners. Essential for production stability and compliance.
Establish reliable, high-availability streaming replication in PostgreSQL with this step-by-step tutorial. Learn how to configure the primary server using `wal_level = replica` and update `pg_hba.conf`. We detail the process of cloning the data directory using `pg_basebackup -R` and verify synchronization using `pg_stat_replication`. This guide ensures your PostgreSQL environment achieves robust data redundancy and failover capabilities using modern configuration practices.
