Tune autovacuum for high-churn PostgreSQL tables. Lower scale factors, monitor dead tuple accumulation, detect wraparound risk, and use pg_stat_progress_vacuum.

Implement least-privilege access in PostgreSQL with role hierarchies, ALTER DEFAULT PRIVILEGES, schema separation, and privilege auditing queries.

Configure PostgreSQL TLS with self-signed or CA-signed certificates. Force TLS via pg_hba.conf, set minimum TLS version, and verify server certs from clients.

Implement PostgreSQL Row Level Security for multi-tenant isolation. Covers USING clauses, WITH CHECK policies, tenant context via set_config, and performance indexing.

pgvector 0.8 delivers significant HNSW indexing improvements and new distance functions. Here is what changed and how to take advantage of it in production.

Measure and reclaim PostgreSQL index bloat using pgstatindex and REINDEX CONCURRENTLY. Learn safe online index rebuilding and autovacuum tuning to prevent future bloat.

A detailed comparison of Google Cloud SQL, Amazon RDS, and Azure Database for MySQL and PostgreSQL — HA architecture, failover times, connection pooling, pricing for equivalent instances, and platform-specific features.

Compare PostgreSQL backup approaches: logical dumps, physical base backups, and WAL-G incremental cloud backups. Covers PITR, restore speed, and backup verification.

Set up PgBouncer in transaction pooling mode to handle thousands of PostgreSQL connections. Configuration, monitoring with SHOW POOLS, and common pitfalls.

PostgreSQL offers multiple index types for different access patterns — and choosing wrong means slow queries or wasted space. A comprehensive guide to indexing strategy, from type selection to monitoring and maintenance.

Configure PostgreSQL logical replication for selective table sync and zero-downtime major version upgrades. Covers publications, subscriptions, and replication slot monitoring.

PostgreSQL disaster recovery requires more than just running pg_dump — it needs WAL archiving, PITR capability, regular restore testing, and clear RTO/RPO targets. Here's how to build it.
