PostgreSQL

PostgreSQL#

This section documents database administration, performance tuning, and schema design for PostgreSQL clusters.

🎛 Core Administration#

• Configuration: Tuning postgresql.conf (shared_buffers, work_mem) for hardware resources.
• Maintenance: Vacuum strategies, index bloat management, and analyzing statistics.
• Security: Role-based access control (RBAC), pg_hba.conf rules, and TLS encryption.

🛠 Operations & HA#

• Replication: Streaming replication setup, logical replication, and failover management (Patroni/Repmgr).
• Backup/Restore: Point-in-time recovery (PITR) using tools like pgBackRest or Barman.
• Extensions: Management of extensions like PostGIS or pg_stat_statements.
