docs: // Sanitize attempts to sanitize passwords out of a raw query.
  // It looks for patterns that may be related to the SET PASSWORD and CREATE USER
  // statements and will redact the password that should be there. It will attempt
  // to redact information from common invalid queries too, but it's not guaranteed
  // to succeed on improper queries.
  //
  // This function works on the raw query and attempts to retain the original input
  // as much as possible.
