Allowing the extra column case is easy:  everwhere in copy.c you find the 
error message "extra data after last expected column", just ignore the 
overflow fields rather than rejecting the line just based on that.  And 
the default information I mentioned you might want to substitute for 
missing columns is already being collected by the code block with the 
comment "Get default info if needed".
