If [type] is [CLIENT_ERROR], [TYPE_ERROR], or [RUNTIME_ERROR], then a backtrace will be provided. The backtrace says where in the query the error occurred. Ideally this information will be presented to the user as a pretty-printed version of their query with the erroneous section underlined. A backtrace is a series of 0 or more [Frame]s, each of which specifies either the index of a positional argument or the name of an optional argument. (Those words will make more sense if you look at the [Term] message below.)
