The reality, though, is that there are a lot of organizations who have invested time and effort into getting a backup
strategyworking using the existing APIs, and there will be quite a bit of pushback against the version in which the
existingexclusive API is removed. 

Some of those will be able to move to non-exclusive backups easily; others won't.  For the ones that can't move easily,
thereaction will not be, "PostgreSQL version x has a safer backup API"; it will be "PostgreSQL version x broke our
backups,so we're not upgrading to it." 

Rather than deprecate the existing API, I'd rather see the documentation updated to discuss the danger cases.
