Summary: Postgres version support tracks the latest major versions, applies minor releases automatically at the next compute restart, and aligns end-of-life with the official PostgreSQL five-year support window. Minor release downgrades and version skipping are not supported. Upgrading to a new major version requires creating a new project and migrating data.

This topic outlines PostgreSQL version support on Neon.

To better understand PostgreSQL version support on Neon, it's helpful to first familiarize yourself with the official PostgreSQL versioning policy and numbering system. You can refer to the official PostgreSQL Versioning Policy documentation for details, but here's a condensed summary:

• The PostgreSQL Global Development Group releases a new major version approximately once per year.
• Each major version is supported for five years from its initial release.
• After five years, a final minor version is released, and the major version reaches end-of-life (EOL) and is no longer supported.

• Minor releases include only bug fixes and security patches, and are issued at least once every three months. Minor releases do not introduce new features.
• The minor release schedule is available in the official PostgreSQL roadmap.
• Critical bugs or security issues may result in an unscheduled release outside the regular minor release roadmap if the issue is deemed too urgent to delay.
• A minor release is issued for all supported major versions simultaneously.
• Occasionally, manual actions are necessary after a minor version upgrade. The PostgreSQL Global Development Group strives to minimize these situations, but they do occur. Any exceptions, required manual steps, or incompatibilities introduced in minor releases are detailed in the PostgreSQL release notes.

• The major version is indicated by the first part of the version number, such as the "18" in "18.1".
• The minor release is indicated by the second part of the version number, such as the "1" in "18.1".

Neon is committed to providing stability and hassle-free maintenance. You select the major version of Postgres when creating a Neon project, and Neon automatically updates your chosen Postgres version to the latest minor release soon after it becomes available. Typically, no user action is required for minor release updates.

Minor release updates are announced in the Neon Changelog.

To check your current Postgres major and minor version, run the following query from the Neon SQL Editor or any SQL client connection to your database:

SELECT version();

The first number is the major version. The second is the minor version, which Neon updates automatically.

Your Postgres major version is also displayed in the Project settings widget on your Neon Project Dashboard. With the Neon CLI installed and authenticated, neon projects get <project_id> --output json returns the same value in its pg_version field.

In Neon, an instance of Postgres runs on each compute in your Neon project. When the PostgreSQL Global Development Group releases a new minor version, Neon automatically updates your computes to the new minor version. Typically, no user action is required for minor version updates. While we aim to make the new minor version available at the same time as the official PostgreSQL release, these updates may occur a few days later than the official release date.

Once a new minor version is available on Neon, it is applied the next time your compute restarts (for any reason). For example, if your compute suspends due to inactivity, the compute will be updated to the new minor version the next time it restarts due to a user-initiated or control-plane initiated action that wakes the compute. If your compute is always active (i.e., it never stops due to regular database activity or because you disabled scale to zero), and you want to force a restart to pick up the latest update, see Restart a compute.

Neon only supports the latest minor release for each major Postgres version. For example, when 18.4 is the latest minor release of Postgres version 18, you cannot choose to run a Neon compute on version 18.3.

Neon does not support skipping minor releases or downgrading to a previous minor release.

The table below shows when recent Postgres releases became available on Neon. Each version links to its PostgreSQL release notes, which list the bug fixes and CVE patches included in that minor release.

The First available on Neon date marks when a release first became available to run, not the point at which every compute is running it; each compute picks it up on the next restart, as described above.

As of August 2026, Neon runs the latest community minor release for every supported major version: 18.6, 17.11, 16.15, 15.19, and 14.24. For the current version list, see Compatibility.

As a managed service, Neon strives to manage all minor version updates automatically, minimizing the need for user intervention. However, certain updates, such as security fixes, may require decisions that depend on your application and cannot be fully automated.

In such cases, your action may occasionally be required. When this occurs, which is infrequent, we will notify you through appropriate communication channels to ensure you are aware of any necessary steps.

Neon currently supports Postgres 14, 15, 16, 17, and 18. Neon supports the five latest major Postgres versions, in alignment with the official PostgreSQL version support policy.

Each Neon project is created with a specific Postgres major version. Upgrading to a newer major version requires creating a new Neon project with the desired Postgres version and migrating your data to the new Neon project. For more information, see Upgrading your Postgres version.
