PostgreSQL Database End of Life (EOL) and Support Versions: What You Need to Know

PostgreSQL, one of the most popular open-source relational database management systems, has been a trusted solution for enterprises worldwide. Like any software, PostgreSQL versions go through a lifecycle that includes regular updates, security patches, and eventually, end of support. Understanding PostgreSQL’s End of Life (EOL) and support schedule is crucial for businesses to ensure security, maintain performance, and stay compliant with the latest standards. This blog will provide an in-depth look at PostgreSQL’s EOL policy and highlight the support provided by EnterpriseDB (EDB), a leading provider of enterprise-grade PostgreSQL services.

Understanding PostgreSQL’s Versioning and Support Policy

PostgreSQL follows a structured versioning system and a well-defined support policy, which has helped make it a reliable choice for critical applications.

• Version Numbering: PostgreSQL versions are identified by a two-part numbering system, for example, PostgreSQL 13.0. Major releases occur approximately once a year, while minor releases (e.g., 13.3, 13.4) are released quarterly and focus on bug fixes and security patches.

• Major Version Support: Each major PostgreSQL version receives five years of support. During this time, the PostgreSQL Global Development Group (PGDG) provides regular updates, including bug fixes, performance improvements, and security patches.

PostgreSQL End of Life (EOL) Policy

Once a major PostgreSQL version reaches the end of its support period, it officially becomes "End of Life" (EOL). After this point, the version no longer receives updates or patches, including critical security fixes. Running an unsupported PostgreSQL version can expose your systems to vulnerabilities and other risks.

Below is an overview of recent PostgreSQL versions and their EOL timelines:

PostgreSQL Version	Release Date	End of Life (EOL) Date
13	Sep 24, 2020	Nov 2025
12	Oct 3, 2019	Nov 2024
11	Oct 18, 2018	Nov 2023
10	Oct 5, 2017	Nov 2022
9.6	Sep 29, 2016	Nov 2021

Note: PostgreSQL 9.6 and older versions are now out of support. Users are encouraged to upgrade to avoid security and performance issues.

Why PostgreSQL EOL Matters for Your Business

When a PostgreSQL version reaches EOL, it becomes outdated, insecure, and potentially non-compliant with regulatory standards. Businesses using an EOL version may face the following issues:

1. Security Vulnerabilities: Without security patches, EOL versions are susceptible to exploits that hackers can target.

2. Lack of Support: Bug fixes and technical support are no longer available, which means issues may become difficult or impossible to resolve.

3. Compliance Risks: Some industries mandate that software be kept up-to-date. Running an unsupported version could result in compliance failures.

4. Missed Features and Performance Improvements: New PostgreSQL versions come with advanced features, better performance, and greater scalability. Older versions limit an organization’s potential for growth.

PostgreSQL Support by EnterpriseDB (EDB)

EDB also offers its own enhanced version of PostgreSQL—EDB Postgres Advanced Server. It comes with added features for security, performance, and compatibility, along with extended support timelines, making it a popular choice for enterprise users looking for extra stability and support.

Key Steps for Managing PostgreSQL EOL Versions

To maintain a stable and secure PostgreSQL environment, consider these steps when a version reaches EOL:

1. Plan Upgrades in Advance: Start planning your upgrade at least one year before the EOL date. This gives your team ample time to test and resolve issues.

2. Test Compatibility: Ensure that your applications, tools, and processes are compatible with the new PostgreSQL version. Use testing environments to identify potential conflicts.

3. Leverage EDB’s Services: If internal resources are limited, consider using EDB’s managed services or extended support to maintain continuity.

4. Prioritize Security: Never ignore security patches. Work with EDB or your internal team to apply security updates promptly.

5. Stay Informed on PostgreSQL Releases: Keep an eye on new PostgreSQL versions and their EOL dates. Being proactive helps avoid last-minute upgrades and disruptions.

Upcoming PostgreSQL Versions and EOL Timelines

With each new version, PostgreSQL introduces new features and enhancements. Staying informed about upcoming releases can help organizations better plan their upgrade schedules. The PostgreSQL Global Development Group typically releases major versions in September each year, so be on the lookout for new features and timelines.

Conclusion

As the PostgreSQL ecosystem continues to evolve, it’s crucial for businesses to stay on top of version support timelines. EOL management for PostgreSQL should be a priority, especially for organizations handling sensitive data or operating in regulated industries. Leveraging EDB’s extended support and managed services can help organizations navigate the PostgreSQL lifecycle confidently.
