> If we know in advance that columns will only be added to but never removed
> from a schema, we can prevent the RPC from the client to the server when the
> client already has all columns declared in the CREATE TABLE/VIEW IF NOT
> EXISTS. To enable this, we can add an APPEND_ONLY_SCHEMA boolean flag to
> SYSTEM.CATALOG. Or another potential name would be IMMUTABLE_SCHEMA to match
> IMMUTABLE_ROWS?
