Comment(by mmetz):

 Replying to [ticket:2051 mlennert]:
 > The -v flag of r.to.vect allows to use the pixel values of a CELL raster
 as category values of the created vector features. In that case and in
 certain circumstances it might not be necessary to create a database table
 for the output vector. It would thus be nice if r.to.vect had an option
 that would allow not to create an attribute table if the -v flag is used.

 Try r57333.

 The change is slightly different than requested: the creation of an
 attribute table can also be suppressed if the -v flag is not used, in
 which case a warning is printed out that raster values will be lost.
 Sometimes it might be useful to just have e.g. areas or lines with a
 unique category and the raster values are no longer needed.
