How would you handle connection errors to a database in a Go application?

Handling connection errors to a database in a Go application requires a robust approach. Using a retry mechanism with exponential backoff is a best practice. This means that when a connection error occurs, the application should make several attempts to reconnect with increasing time intervals between attempts. This increases the likelihood of successfully reestablishing the connection when the database becomes available again. Ignoring errors or using a static timeout can lead to poor reliability and application crashes. Using a single connection for the entire application is generally not recommended as it can lead to performance bottlenecks and issues with resource management.
