PostgreSQL is the most advanced open-source relational database – and increasingly the go-to choice as the foundation for modern web applications, APIs, e-commerce systems, and analytics platforms. It offers advanced data types (JSONB, arrays, geometric types), full-text search, ACID transactions with MVCC isolation, streaming replication, and point-in-time recovery.
At WebOptimo, we provide professional PostgreSQL administration – from tuning server configuration and query optimization, through designing backup strategies with WAL archiving, to configuring replication and 24/7 performance monitoring.
The default PostgreSQL configuration is designed for maximum compatibility, not performance. We tune key parameters: shared_buffers (usually 25% of RAM), work_mem (for complex queries), effective_cache_size, maintenance_work_mem, wal_buffers, checkpoint_completion_target. We select each parameter based on workload analysis, database size, and query profile.
We use pg_stat_statements to identify the most frequent and slowest queries, and EXPLAIN ANALYZE to analyze execution plans. We add missing indexes (B-tree, GIN for JSONB, GiST for spatial data), optimize complex queries with CTEs and window functions, and configure partitioning for large tables. Every optimization is measured and verified – we describe the details in our publication PostgreSQL performance tuning.
Autovacuum is a key PostgreSQL process – it recovers space from dead tuples and updates query planner statistics. If poorly configured, it leads to table bloat, performance drops, and excessive disk usage. We adjust autovacuum_vacuum_threshold, autovacuum_vacuum_scale_factor, and autovacuum_naptime to the database size and write intensity. We monitor bloat and react proactively.
We perform PostgreSQL backups using pg_dump, pg_dumpall, and pg_basebackup. For production environments, we configure continuous WAL (Write-Ahead Log) archiving, enabling point-in-time recovery – restoring the database to any exact moment in time, down to a single transaction. We store copies locally and remotely with encryption and retention rotation – in ZFS environments, we apply additional optimizations described in our publication ZFS optimization for PostgreSQL and MySQL.
We configure PostgreSQL streaming replication – synchronous and asynchronous. A hot standby read replica relieves the main server, while a warm standby ensures disaster recovery with minimal RPO. For advanced scenarios, we deploy logical replication – selective replication of specific tables or databases, zero-downtime migration, and PostgreSQL version upgrades without downtime.
We monitor key PostgreSQL metrics 24/7: transactions per second, shared_buffers usage, cache hit ratio, slow queries, active connections, dead tuples and bloat, and replication lag. We secure database access: configuring pg_hba.conf, SSL/TLS, roles and permissions based on the principle of least privilege, and connection encryption.
PostgreSQL is a database that rewards proper configuration and punishes neglect. Default shared_buffers set to 128 MB, disabled pg_stat_statements, and factory autovacuum thresholds on a database with millions of rows is a recipe for performance issues that build up gradually and appear at the worst possible moment. We administer PostgreSQL with attention to every parameter, knowing that a well-configured database is the foundation of a fast and reliable application. For environments requiring high availability, we deploy HA clusters – details in our publication PostgreSQL replication and high availability.
PostgreSQL administration at WebOptimo is a repeatable, structured process – not a one-time intervention.
PostgreSQL is a powerful database, but without regular administration, even the best-designed application loses performance. Here are common situations where professional support pays off.
The application ran fast with a thousand records, but at a million, queries take seconds instead of milliseconds. Missing indexes, untuned work_mem, and outdated planner statistics are the most common causes. An audit with EXPLAIN ANALYZE and pg_stat_statements pinpoints specific bottlenecks.
Default autovacuum thresholds are not tailored for intense write operations. Dead tuples accumulate, tables grow faster than they should, and queries scan more and more unnecessary data. Tuning autovacuum to the actual workload profile eliminates the problem at its source.
More and more teams are moving to PostgreSQL due to JSONB, window functions, CTEs, and better data integrity. Migration is more than just running pgloader — you need to redesign indexes, test queries, tune the configuration, and verify performance on the new engine. We handle migrations with minimal downtime.
A single PostgreSQL instance is a single point of failure. For applications that cannot afford downtime, we deploy HA clusters with Patroni, etcd, and HAProxy – featuring automatic failover, split-brain protection, and a read replica that offloads the primary server.
Developers write the application, but no one tunes PostgreSQL, analyzes slow queries, or tests backups. Version upgrades are postponed, monitoring is limited to "it works / it doesn't". We take over PostgreSQL administration as an external DBA – with regular tuning, monitoring, and reporting.
Supabase, AWS RDS, Google Cloud SQL – managed PostgreSQL takes away some of the work, but does not relieve you of responsibility for query tuning, indexes, and data architecture. We help choose the deployment model and manage PostgreSQL wherever it runs – we describe Supabase's architecture in our publication Inside Supabase.
PostgreSQL is a better choice when an application requires advanced data types (JSONB, arrays, geometric types), complex queries with CTEs and window functions, full-text search, ACID transactions with MVCC isolation, or high data integrity. PostgreSQL is perfect for web applications, e-commerce systems, APIs, and anywhere a relational database is a key architectural component.
WordPress natively requires MySQL or MariaDB. There are plugins that allow it to work with PostgreSQL (e.g., PG4WP), but it is not an officially supported configuration and can cause plugin compatibility issues. We recommend PostgreSQL for custom web applications, APIs, and e-commerce systems built outside of WordPress. For WordPress and WooCommerce, MySQL or MariaDB is a better choice.
Optimization includes tuning server configuration (shared_buffers, work_mem, effective_cache_size, maintenance_work_mem, wal_buffers), analyzing slow queries using pg_stat_statements and EXPLAIN ANALYZE, adding indexes (B-tree, GIN, GiST), configuring autovacuum, optimizing the query planner, and partitioning large tables.
We perform PostgreSQL backups using pg_dump (logical database dump), pg_dumpall (all databases and roles), and pg_basebackup (full physical cluster copy). For large databases, we use incremental backups with WAL (Write-Ahead Log) archiving, enabling point-in-time recovery – restoring the database to any specific moment in time. We store copies locally and remotely with encryption.
Yes. We configure PostgreSQL streaming replication – synchronous and asynchronous. Streaming replication allows for creating a hot standby (read replica) and warm standby (disaster recovery). For advanced scenarios, we configure logical replication, which allows replicating specific tables or databases.
Autovacuum is a PostgreSQL process responsible for recovering space from deleted and updated rows (dead tuples) and updating query planner statistics. A poorly configured autovacuum leads to table bloat, decreased query performance, and excessive disk usage. We adjust autovacuum parameters to the database size and write operation intensity.
Yes. We administer PostgreSQL on VPS and dedicated servers with any provider, as well as on managed cloud services – AWS RDS, Google Cloud SQL, DigitalOcean Managed Databases. We help choose between self-hosted and managed PostgreSQL depending on performance requirements, budget, and administrative needs.
We will present a PostgreSQL administration and optimization offer tailored to your needs. No obligations, no marketing jargon – a concrete proposal after a short conversation or database analysis.
