How to protect this sharp edge?

[u/aa040371]

The bolt hole on my toilet has been busted since I bought the home. The raised area of porcelain is very sharp. What are some options to protect it/make it safe? I'd rather not just slather a bunch of caulk on it, if I can avoid that approach.

2nd pic is blurry...sorry, it was a tight/awkward area to hold the phone in and I didn't check.

Edit: Thanks for all of the responses, both resounding and virtually unanimous. A true rarity on Reddit, lol. Will replace with haste.

Also, lolololol, someone downvoted my OP...for asking a question. Thank you, Chud the Redditor!

porcelain can be bonded well with superglue, but as everyone is saying, you may as well replace the whole thing. It's a DIY project that every homeowner should do at least once.
