This is the first notable, semi-reputable Google result for each "${COMPANY_NAME} data breach". Some of these are examples of an API being leveraged to exfiltrate database records rather than direct database breaches like getting the admin password to postgres.

If you want to see more for the same company, try appending "-{YEAR_OF_KNOWN_DATA_BREACH}" to skip the ones you've already read, though this will tend to exclude companies who have multiple data breaches in one year.
