PostgreSQL

The world's most advanced open-source relational database

https://www.postgresql.org

What It Is

PostgreSQL is the world’s most advanced open-source relational database, known for its reliability, feature richness, and extensibility. Beyond traditional OLTP workloads, PostgreSQL supports JSON documents, time-series data (TimescaleDB), geospatial queries (PostGIS), full-text search, and even vector similarity search (pgvector) — making it an incredibly versatile foundation for data architectures.

How We Use It

PostgreSQL is a cornerstone of our data stack. We use it as the application database for our own platforms (including DMP.AF), as a metadata store for orchestration tools, as a lightweight analytical backend for smaller-scale workloads, and as a source system for extraction pipelines. Our deep PostgreSQL expertise ensures we get the most out of this versatile database in every context.

Our Expertise

✓
Performance Tuning

We optimize PostgreSQL for demanding workloads: query plan analysis (EXPLAIN ANALYZE), index strategies (B-tree, GIN, GiST, BRIN), query rewriting, CTE optimization, and statistics tuning.
✓
Indexing Strategies

We design partial indexes, expression indexes, covering indexes, and multi-column indexes tailored to actual query patterns.
✓
Partitioning & Scaling

We implement declarative partitioning, design partition strategies (range, list, hash), and evaluate solutions like Citus for horizontal scaling.
✓
Replication & High Availability

We set up streaming replication, logical replication, and Patroni-based HA clusters.
✓
Extensions Ecosystem

We leverage TimescaleDB for time-series, PostGIS for geospatial, pgvector for AI/ML embeddings, and pg_stat_statements for monitoring.
