shared_preload_libraries is blocked in postgresql.parameters, and rightly so: the parameter is free text and accepts a path, so it can point at a writable location such as the PGDATA volume. What the block leaves is an indirect route. CloudNativePG preloads pg_stat_statements, auto_explain and pgaudit by itself as soon as a parameter under their prefix is set, such as pg_stat_statements.track, so enabling one of them today means setting one of its tuning parameters, even to its default value. pg_prewarm has no route at all, and its autoprewarm worker only runs when the module is preloaded. postgresql.sharedPreloadLibraries is the explicit switch. It is a closed enum of four module names that already ship in the CloudNativePG PostgreSQL image, rendered onto the CNPG Cluster field of the same meaning, which the operator merges with the libraries it preloads on its own. A bare name can only resolve inside $libdir, which sits on the read-only image filesystem, and dynamic_library_path stays blocked, so no path can be introduced. The blocklist on postgresql.parameters is left untouched. The template repeats the enum as a backstop for renders that skip schema validation. helm-unittest always validates the schema and never reaches it, so a bats suite renders with --skip-schema-validation to keep the backstop, and its agreement with the enum, under test. Verified on a live CloudNativePG 1.27.3 cluster: with the field set, the operator writes shared_preload_libraries into postgresql.conf, SHOW reports the modules, and pg_stat_statements returns rows. Changing the list restarts PostgreSQL on every instance, the primary included, through the instance manager and without restarting the pod.
