Aw, it's not that dangerous ;-).  You can improve your odds considerably
if you issue BEGIN; before you start dorking with the system tables,
and COMMIT only after you're satisfied you have things right.  If you
realize you blew it, ROLLBACK.

Still, I'd recommend practicing on a scratch database before you do it
for real.
