Are you overthinking the problem? Adding a column without a default
doesn't do any row updates and shouldn't fire any triggers. I'm not
sure that adding a column *with* a default will fire update triggers
either. (That might be a bug, if so ...)
Suggest testing before assuming you have a problem to solve.
