I imagine it would not be a totally happy thing if the only way to switch it on/off was to use Slony or Londiste to replicate into a database with the opposite setting. (e.g. - This implies that built-in replication may only replicate into a database with the identical checksum configuration.) It's not outrageous for it to be a pretty heavyweight operation to switch polarities, but there's such a thing as too heavy. -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"
