   v.db.renamecol renames a column in the attribute table connected to a
   given vector map. It automatically checks the connection for the
   specified layer.

ÐÐ ÐÐÐЧÐÐÐЯ

   If the map table is connected through the DBF or SQLite drivers, the
   renaming is internally done by adding a new column with new name,
   transferring the contents of the old column to the new column and
   dropping the old column. This is needed as DBF or SQLite do not support
   "ALTER TABLE" command to rename columns. Due to this the renamed column
   is found as last column of the table, it's original position cannot be
   maintained.

   The SQLite driver will exit with an error if the column rename involves
   only a change of case, i.e., upper-to-lowercase, or lower-to-uppercase.
   The SQLite protocol considers "NAME" and "name" to be identical column
   names. In cases like these, the user should rename the original column
   to an intermediary name, then rename the intermediary to the final
   name.
