Someone with the MAINTAIN privilege on a table can use search_path tricks against the table owner, if the code is susceptible, because maintenance code runs with the privileges of the table owner.
Only change the search_path if someone other than the table owner or superuser is running the command (which should only be possible via the new MAINTAIN privilege)?
