Exactly--especially since on a properly configured system, you won't
even see the "cardid" (or cardinputid). You should assign names to your
inputs, and they'll be called--whatever you named them. (This assumes
that "properly configured" means you've assigned a name since you didn't
want to see the "default" names.)

I haven't posted this often enough this week, so as long as it's
relevant here (though already nicely summarized):

Not to mention all the things you could break (depending on the
specifics of your configuration). Hacking the DB data should only be
attempted by people who are familiar enough with the internal workings
of MythTV to know better than to hack the DB data...
