I was able to get it to work by using v.db.renamecolumn to rename columns that would be duplicates when truncated by v.patch.
I am kind of surprised we can only use columns with 10-characters, and using v.patch uses two of the characters (it appends a_ etc.). 8 characters isn’t exactly a lot. Is there are reason why columns have this limitation?
