In PostgreSQL 10 - when using an "owner user" (login role owning a schema and all tables, not used by the application at runtime) and a "runtime" user I can
GRANT Select/Update/Delete permissions on all existing tables in the schema to the runtime user:
GRANT SELECT ON ALL TABLES IN SCHEMA owner TO runtime;
But this only applies to existing objects and not new tables which might get created later on.
Is there a way to avoid granting on all new objects by way of inheriting roles or schema permissions or similar?
