# PostgreSQL 15.19 and 17.11 minor releases with security updates and breaking changes

> Supabase rolled out PostgreSQL 15.19 and 17.11 minor releases that close 44 CVEs and include correctness fixes. Four changes may require action: ltree indexes need reindexing on multibyte/ICU databases, pgcrypto legacy ciphers are no longer decryptable by default, btree_gist indexes on float columns with NaN need reindexing, and custom operators require superuser to recreate.
