Subject: Bug: Specify DictCursor class to return dict-like result

Without specifying the `cursorclass`, the result is a tuple of the
form:

    ((query_col01_val, query_col02_val, ...), ...)

where the ellipsis specify the possibility of more than one of the
previous form.

We specify the DictCursor class instead so that the form changes to:

    ({query_col01_name: query_col01_val, ...}, ...)

which allows us to pick the value we want with a string index.
