 option already exists, but the module wants to create a new table. This is
 why the module fails.

 Where do you see a table that already exists ? The table to be created is
 same4. The module complains about a column 'loc_dist' that already exists
 which comes from the create table statement where the creation of that
 column is asked for twice:

 'create table same4 (from_cat integer, to_cat integer, loc_dist double
 precision, loc_dist double precision )'

 And the problem goes away when the OP tries again (creating table same5),
 but without using to_attr in upload. This looks exactly like #672 to me (I
 didn't put the error message in #672, but it's exactly the same as you can
 see if you try with grass6.)
