Being supported means fixes keep shipping to this branch. Here is the stream that stops. Source: NVD.
PostgreSQL CVEs published and patched, by year
44 published in the last 12 months · data refreshed 2026-10-05
At the last-12-month rate of 44 PostgreSQL CVEs, running 16 for a year past 9 Nov 2028 means roughly that many vulnerabilities fixed upstream but never backported to your branch. Past branches bear this out: PostgreSQL 13 has missed 44 since it went end of life.
How much runway a newer branch buys
Moving to PostgreSQL 18 extends security support by about 735 days.
