Why? Sure, the DBA had better be damn certain that he wants to do that
before he does it. But we let superusers drop lots of things that they
would be better advised not to. If someone wants a small disk footprint
I can imagine a good case for feeling that information_schema is useless.

Rely away. It's not your business to work in databases that a superuser
has made arbitrary changes to. Do you claim to still work if he renames
the integer "=" operator to "!#&@!!" ?
