🔄 PostgreSQL PITR implementation secrets:

• WAL-E/WAL-G for automated WAL archiving to S3/GCS
• recovery_target_time for precise point-in-time recovery
• Continuous archiving with archive_command prevents data loss
• Base backups + WAL replay = recovery to any second
• Test your recovery process monthly - backups without testing are just hopes

Recovery time: minutes, not hours ⚡

🚀 Linux Tip: Transparent Huge Pages (THP) can negatively impact database performance.

THP automatically creates 2MB pages vs standard 4KB, but causes:
❌ Memory fragmentation
❌ Allocation delays
❌ Unpredictable latency spikes

Disable with: echo never > /sys/kernel/mm/transparent_hugepage/enabled
