## The brief

Supabase's rollout of PostgreSQL 15.19 and 17.11 brings security fixes alongside compatibility changes that may require database maintenance. The notice identifies affected ltree and btree\_gist indexes, legacy pgcrypto PGP ciphers, and custom operators using nonstandard selectivity estimators. It provides detection queries and migration steps; impact depends on those features being used. Dashboard upgrades and new-project versions became available September 28, according to the rollout schedule.
