What the Book Covers
Installation and Configuration
Step-by-step installation on Ubuntu, Debian, AlmaLinux, and Docker environments. Covers postgresql.conf tuning for different workload profiles — OLTP, OLAP, and mixed workloads.
# Key postgresql.conf settings for production
shared_buffers = '4GB' # 25% of total RAM
effective_cache_size = '12GB' # 75% of total RAM
work_mem = '256MB' # Per-operation memory
maintenance_work_mem = '1GB' # For VACUUM, CREATE INDEX
wal_buffers = '64MB' # WAL write buffer
max_connections = 200 # Based on your needs
random_page_cost = 1.1 # For SSD storageSecurity and Authentication
Configure pg_hba.conf for secure access control, set up SSL encryption, implement role-based access control, and manage user permissions following the principle of least privilege.
Backup and Recovery
Master multiple backup strategies — pg_dump for logical backups, pg_basebackup for physical backups, and continuous archiving with WAL for point-in-time recovery.
# Automated daily backup script
pg_dump -h localhost -U admin -F c -b -v \
-f "/backups/mydb_$(date +%Y%m%d_%H%M%S).dump" mydb
# Point-in-time recovery setup
archive_mode = on
archive_command = 'cp %p /archive/%f'Performance Optimization
Learn to use EXPLAIN ANALYZE, identify slow queries, create effective indexes, and monitor database performance with pg_stat_statements.
Replication and High Availability
Set up streaming replication, logical replication, and failover strategies for production environments that require high availability.
