I am wondering what the best way is to force character data to a specific case, like upper case for example. Is a trigger or rule the only option? Would a check constraint be better or faster than using rules or triggers, knowing that a check constraint puts the onus back on the client code to ensure the data is in the correct case?
For something like this I would think triggers would be more robust and I wouldn't expect the performance overhead to be that great.
