# LeanKG Postgres deployment (Phase 8, plan D4): PostgreSQL + pgvector is the
# only storage engine. `docker compose up` brings up the postgres service; the
# leankg service mounts your project and connects via LEANKG_PG_URL.
#
# The legacy embedded-RocksDB / cozoserver compose files were removed in Phase 8.
