PostgreSQL at Shivacha
Our default relational database — reliable, extensible and strongly consistent.
Overview
PostgreSQL is our default choice for transactional systems, including financial ledgers. It combines strong consistency and ACID transactions with extensions for JSON, full-text search and vectors. We design schemas, indexes and partitioning for scale and plan backups and replication for resilience.
Why we use it
- ACID transactions
- Rich extension ecosystem
- JSON and vector support
- Proven at scale
