PostgreSQL 18 End of Life Date
PostgreSQL 18 end-of-life date, support status, and CVE risk. Data from endoflife.date and official vendor documentation.
PostgreSQL 18 was released on September 25, 2025 and support is scheduled to end on November 14, 2030 — a planned supported lifespan of 5 years and 2 months, in line with the 5 years and 1 month median for PostgreSQL releases. Its most recent patch is 18.4, published May 11, 2026.
What does PostgreSQL 18 end of life mean?
When PostgreSQL 18 reaches end of life, the maintainers stop issuing security patches for this version. CVEs discovered after the EOL date are publicly disclosed on the National Vulnerability Database with no patch available. Exploit code frequently appears on GitHub within days of disclosure.
The CVE blind spot: Most vulnerability scanners check for known CVEs but do not flag the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Running PostgreSQL 18 past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to PostgreSQL 18 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
