Review Comment:
let's assume `foo.bar` namespace exists.
If I call `list_namespaces("foo")` I should get [("foo", "bar")] in the
result so my query should look like:
`SELECT .... FROM ... WHERE table_namespace LIKE 'foo%'` and not
`SELECT .... FROM ... WHERE table_namespace LIKE 'foo'`.
JdbcCatalog also adds `%`.
