This sounds like you are describing something written. Can you provide a

Which community? There are many ways in which a "data schema [can be]
presented as data". In PostgreSQL there is only a single source of truth
for what the data schema is - the "System Catalogs" [1]. Those tables are
made available to the user in the pg_catalog schema.
