> I got an incorrect result with this query:
> {noformat}
> >>select * from udf(echo(table(select * from (values (1), (22), (3), (4))
> >>t(x))));
> X
> ------
> 1
> -234
> 3
> 772
> --- 4 row(s) selected.
> >>
> {noformat}
> Note that -234 if FF16 (and 16 is hex for 22) and that 772 is 304, so it's a
> junk byte followed by the true values 22 and 4 that is returned.
