<p>Dear list,</p>
<p><br>
</p>
<p>in GRASS 7.8 v.to.db creates a new column in contrast to previous
versions where it column had to exist before.</p>
<p>According to the manual "If the <em>column</em> exists, the
<b>--overwrite</b> flag is required to overwrite it". However,
this flag does not exist. Hence, if the column is present, it is
not upated, giving:<br>
</p>
<p>ERROR: Column <length_new> exists. To overwrite, use the
--overwrite flag</p>
<p>When useing "overwrite", it gives:</p>
<p>Invalid flag value: overwrite</p>
<p><br>
</p>
<p>Another issue is that even if the flag would work, it would no
longer be compatible with previous versions that also do not know
the flag but need the column to exist.</p>
<p><br>
</p>
<p>Can anybody please advice me what to do?</p>
<p><br>
</p>
<p>Thanks,</p>
<p>Mira<br>
