This comment is a thinko, it refers to XLOG_BACKUP_END. This comment block could be reworded a bit, it looks cleaner to me to say "ControlFile->backupEndRequired is false" instead of just referring to the variable itself. Worse, the current comment implies that minRecoveryPoint is incorrectly set if it is true. Bleh. -- Michael
