create_data_dir_secure: Create a database data directory with owner-only permissions.
validate_data_dir_read_only: Validate that data_dir is an existing directory suitable for read-only snapshot serving, without mutating it. Unlike create_data_dir_secure this never creates the directory and never calls set_permissions: a read-only open must leave the directory byte-for-byte unchanged. It only confirms the path exists and is a directory; the actual read access is then proven by opening the catalog and heap files read-only.
