PostgreSQL Consulting
PostgreSQL has become the first choice for enterprise workloads thanks to its extensibility, data integrity and query planner. Misconfigured, however, bloat, vacuum problems and plan regressions silently erode performance. We've fixed these problems in production many times over.
Whether you're building a new PostgreSQL architecture, improving an existing cluster or planning a migration from Oracle/MySQL — we take on the entire process, from schema design to high availability.
What we do
- Query plan analysis, index strategy and planner tuning
- VACUUM / autovacuum tuning, bloat cleanup and table maintenance
- Partitioning design and large-table management
- High availability with Patroni and automatic failover
- Logical replication, version upgrades and zero-downtime cutover
- Oracle / MySQL to PostgreSQL migration with data validation
Frequently asked questions
Why do our PostgreSQL tables keep growing (bloat)?
Due to MVCC, updated/deleted rows don't free space immediately; if autovacuum can't keep up, bloat accumulates. We tune autovacuum thresholds to your workload, clean up with pg_repack without downtime where needed, and set up monitoring to prevent recurrence.
Is migrating from Oracle to PostgreSQL realistic?
For most workloads, yes — and it cuts licensing costs dramatically. The critical step is an inventory of PL/SQL code and Oracle-specific features: what converts automatically and what needs rewriting must be clear up front. We run the compatibility analysis and produce a phased migration plan.
What do you recommend for PostgreSQL high availability?
Our production standard is streaming replication + Patroni for automatic failover, fronted by HAProxy/pgBouncer. Depending on your RPO/RTO targets we add synchronous replication and geographic redundancy; every scenario is validated with drills.
Queries are sometimes fast, sometimes very slow — why?
The usual suspect is changing query plans caused by stale statistics. We make behavior predictable through ANALYZE frequency, statistics targets and plan stabilization where necessary, and record regressions with auto_explain.
