For now the internal function BackupInProgress() only return a boolean.
I like the idea that pg_is_in_backup() just works as pg_is_in_recovery()
do. I mean it doesn't return the timestamp of the recovery starting time
but only true or false.
Maybe we can have an other function that will return all information
available in the backup_label file ?
