PostgreSQL Optimization & Configuration

Production-optimized PostgreSQL with: configuration tuning for your hardware and workload (shared_buffers, work_mem, effective_cache_size, WAL settings), indexing strategy based on query analysis, PgBouncer connection pooling, streaming replication for read replicas and HA, automated backups with point-in-time recovery (pgBackRest or WAL-G), monitoring with pg_stat_statements, and vacuum tuning.

We tune PostgreSQL parameters based on your server's RAM, CPU cores, storage type (SSD vs HDD), and workload pattern (OLTP vs OLAP). shared_buffers gets 25% of RAM. effective_cache_size accounts for OS cache. work_mem is sized for your query complexity. max_connections is set realistically (usually much lower than the default of 100). WAL configuration balances write performance with durability.

We analyze your query patterns using pg_stat_statements and EXPLAIN ANALYZE to identify missing indexes, unused indexes (wasting write performance), and suboptimal index types. B-tree indexes for equality and range queries, GIN indexes for full-text search and JSONB, GiST indexes for geometric and range types, and partial indexes for queries with WHERE clauses on specific values. Each index justifies its maintenance cost.

PostgreSQL forks a process per connection — 200 connections means 200 processes consuming memory and CPU. PgBouncer sits between your application and PostgreSQL, multiplexing hundreds of application connections onto a smaller pool of database connections. Transaction mode pooling provides the best performance for most applications. We configure pool sizes based on your query patterns.

Streaming replication provides read replicas for horizontal read scaling and hot standby for high availability. Synchronous replication ensures zero data loss for critical workloads. pgBackRest or WAL-G provides automated backups with incremental strategy, compression, and point-in-time recovery capability. Backup verification runs on schedule to ensure recoverability.
