A moment of fatigue led to a significant mishap in a production database, resulting in the loss of approximately 30% of revenue. This incident prompted the creation of an open-source PostgreSQL backup and monitoring tool called Postgresus, which is built using Go, gin, gorm, React, TypeScript, and PostgreSQL, and packaged in Docker. The tool allows for scheduled backups, storage in cloud options, and notifications about backup success or failure. It also alerts users if the database becomes unresponsive. The creator experienced a database corruption incident in 2023 while managing a pet project, which resulted in the overwriting of user emails and significant operational challenges. The initial version of the backup tool was developed in Java but later transitioned to Go for improved performance. The project aims to enhance PostgreSQL monitoring and expand notification channels and storage support. The creator has adopted safety rules for database management, including performing a SELECT before executing an UPDATE and conducting restoration drills every three months.
