     'dbColumnInfo' is a generic function that, when called on a result
     object, returns type information about tuple fields in the result.

_U_s_a_g_e:

     dbColumnInfo(result)

_A_r_g_u_m_e_n_t_s:

  result: A query result object.

_V_a_l_u_e:

     Returns a data frame with each row corresponding to a different
     field in the result.  Rows are named for each field.  Any
     available information about a field can be presented in columns of
     the data frame.  The most important of these is probably a "Type"
     column that can be used to convert strings returned by the query
     into appropriate R types.
