Executive Summary
Enterprises across BFSI, retail, and healthcare are rapidly shifting from Oracle to PostgreSQL in 2025. What was once seen as risky is now a clear strategy for cost savings, cloud-native flexibility, compliance, and reliability. With Oracle’s high licensing costs limiting innovation, PostgreSQL offers a license-free, open-source alternative that scales across on-prem, hybrid, and multi-cloud environments. Backed by compliance support and a strong ecosystem, PostgreSQL has become the smarter choice for modern enterprises.
This article explores why the shift is accelerating and what it means for the future of enterprise databases.
1. Cost and licensing advantages
Cost is a prime motivator to make an exit from being locked into Oracle.
- High licensing burden: Oracle’s per-core licensing and additional charges mount rapidly and push enterprises into expensive contracts with very little negotiation power.
- Audit and renewal risks: Occasional audits and surprise compliance checks create literal financial uncertainty.
- License-Free Advantage: PostgreSQL being open source and free decreases the costs while using it. Enterprises pay only for infrastructure and optionally for managed services.
- TCO Reduction of Up to 90 Percent: Organizations often report major savings of TCO once the migration is completed. And the benefits extend beyond just licensing to hardware, scaling, and even support.
- Industry Example: A retail chain that migrated away from Oracle avoided huge renewal fees and diverted the money to IT innovations for its customers.
PostgreSQL tops Stack Overflow’s 2024 survey, with ~49% adoption, reflecting strong talent and community momentum for migrations.
DB-Engines’ Q1 2025 ranking names PostgreSQL a fastest-growing database, fuelled by enterprise adoption in BFSI, retail, and healthcare.
2. Cloud native scalability and flexibility
Modern enterprises need databases that work hybrid and multi-cloud seamlessly. Oracle, with its on-premises predominance and vendor-controlled cloud paradigm, often limits this choice. Contrarily, PostgreSQL is made for the cloud-first world of today
- Cloud Portability: PostgreSQL can run on AWS, Azure, GCP, and private clouds without proprietary lock-in, hence true multi-cloud freedom.
- BFSI transformation: The banks of the modern world that are upgrading their core banking system prefer to use PostgreSQL such that they can go full scale on cloud-native microservices without depending on the rigid Oracle ecosystem.
- Retail agility: E-commerce platforms and omnichannel retailers work on PostgreSQL so that they get quick scaling during seasonal peaks such as holidays or sale events.
- Healthcare Interoperability: Hospitals and research centres use PostgreSQL in support of cloud-based patient record systems that integrate with HL7 and FHIR standards quite easily.
- High scalability: PostgreSQL provides horizontal scalability, partitioning, and load balancing so the consistent level of performance can be maintained even while a very high transaction volume exists in the system.
3. Security and compliance, and reliability
Security and compliance are paramount in regulated industries like BFSI and healthcare. Enterprises must comply with stringent regulations such as HIPAA, PCI-DSS, and GDPR. PostgreSQL has evolved into a database platform that not only meets all these requirements but often exceeds them.
- Advanced security features: Postgres gives you the option to encrypt data both in transit and while at rest; it allows for role-based access control, row-level security, and detailed auditing.
- Compliance with regulations: Where a large number of compliance regulations are to be satisfied, the system provides out-of-the-box support for HIPAA, PCI-DSS, and GDPR, so enterprises need not bid on costly customizations.
- Enterprise-grade reliability: PostgreSQL provides high availability, automatic failover, advanced indexing, partitioning, and JSON, making it suitable for mission-critical workloads.
- BFSI use case: Banks use PostgreSQL systems for fraud detection, applying real-time analytics to massive transaction datasets.
- Retail use case: Retailers implement PostgreSQL with AI/ML for personalized product recommendations and demand forecasting improvement.
- Healthcare use case: Hospitals try to manage patient data securely with PostgreSQL and AI-powered diagnosis, staying compliant with the stringent norms of the healthcare industry.
Gartner’s 2024 survey shows most IT leaders use and plan to expand open-source DBMS, cementing PostgreSQL as a top enterprise choice.
FAQs:
Why are enterprises moving from Oracle to PostgreSQL in 2025?
Enterprises across BFSI, retail, and healthcare are shifting to PostgreSQL to reduce licensing costs, gain cloud-native flexibility, and meet compliance needs more efficiently than Oracle.
How much cost savings can businesses expect by migrating from Oracle to PostgreSQL?
Organizations often report up to 70–90% total cost reduction, factoring in licensing, hardware, scaling, and support costs. Actual savings depend on the enterprise’s size and setup.
Is PostgreSQL secure enough for regulated industries like BFSI and healthcare?
Yes. PostgreSQL offers advanced security features like data encryption, row-level security, and role-based access control. With proper configuration, it meets HIPAA, PCI-DSS, and GDPR compliance standards.
Can PostgreSQL handle mission-critical workloads at enterprise scale?
Absolutely. PostgreSQL supports high availability, automatic failover, partitioning, and horizontal scalability, making it reliable for large-scale, mission-critical workloads.
