I thought `current_database` was returned via client=facing APIs, however, now I see it is used only in the internals.

However, it looks like the specific usage could be completely removed from SQL and we could use something like 

```java
byte[] catalogName = /* rs.getBytes("current_database") */; // replace with a known literal
...
tuple[0] = catalogName;
```
