Developer Tool
Every supported PostgreSQL major version's end-of-life date, with a live countdown to whichever is coming up next.
PostgreSQL ships one new major version every year, and each major version receives exactly 5 years of support from its initial release — after that, the PostgreSQL Global Development Group stops issuing security and bug fixes for it entirely, even for critical vulnerabilities. Because the yearly cadence is predictable, EOL dates for versions several years out are already fixed on the official schedule.
Unlike some vendors, there's no extended or paid support tier from the PostgreSQL project itself — once a version passes EOL, upgrading to a supported major version is the only way to keep receiving fixes from upstream. Some managed cloud providers (RDS, Cloud SQL) offer their own extended support windows past the community EOL date, but that's a separate, provider-specific arrangement.
