Prior to this patch, a synthetic OID was used for
"namespace" (schema) references in `pg_catalog`.
This was making it difficult/impossible to retrieve
schema comments using a non-`root` SQL query, e.g. via
```sql
SELECT nspname AS schema,
substr(coalesce(pc.comment, sc.comment), e'[^\n]{0,40}') as description
FROM pg_catalog.pg_namespace t
LEFT OUTER JOIN system.comments sc
ON t.oid = sc.object_id AND sc.type = 4
LEFT OUTER JOIN crdb_internal.predefined_comments pc
ON t.oid = pc.object_id AND pc.type = 4
```
This patch fixes it.
