Review Comment:
Same logic as previous just indented under the `if cols:` statement. Unlike
Presto where `get_indexes` returns `[]` for a non-partition table, Trino
returns `[{'name': 'partition', 'column_names': [], 'unique': False}]`. Rather
than overriding the engine specific `normalize_indexes` method I though it
would be more prudent to make this method more robust given there was already
an expectation that there may be no columns associated with the index, i.e., a
non-partitioned table.

Review Comment:
This should never have been a `pyhive.exc` exception to begin with.
