Neglecting to apply this update could leave servers vulnerable to attacks, as the security flaws pose significant risks to production environments

PostgreSQL 18.2 Security Patches & Critical Bug Fixes Explained

PostgreSQL 18.2 (and the matching updates for 17.8, 16.12, 15.16 and 14.21) patches five high‑severity security flaws—including remote code execution bugs in the intarray, pgcrypto, multibyte handling and pg_trgm extensions—so any server running those versions is exposed until upgraded. The release also fixes over 65 bugs, notably ltree case‑insensitive index errors, a broken NOT NULL constraint addition, and backup failures on tables larger than 1 GB. Upgrading is straightforward: stop the service, replace the binaries, start again, then reindex any ltree columns if you use non‑libc collations. Skipping this minor release leaves critical attack surfaces open while offering little upside.
