Indeed eliminating irrelevant suggestions would improve user experience, but I think there is a drawback that it increases code maintenance for adding options used both in COPY FROM and TO. This might be trivial until the number of common options are small as now, though. Perhaps, the redundant code could be reduced by preparing a list (an array of const char*) containing common options part, then appending options specific to each mode using some function like kind of append_variable_names, and passing these lists to COMPLETE_WITH_LIST.
