Descriptor information

Describe the bug
The structure of a result set obtained from cursor.fetchall is supposed to be returned in the cursor.description component.
The header names are there, but also some types, ... dtype('O'), dtype('O'), dtype('bool')..

Other properties seems not yet available
display_size=None, internal_size=None, precision=None, scale=None, null_ok=None

Expected behavior
Given that the interface is geared at the SQL world, I would like to see the SQL type information
to be able to interpret/re-use it properly.
