Safe Data Changes in PostgreSQL
Hi HN, we're excited to share our open source tool with the community! We previously posted here with the tagline “real-time events for Postgres” [0]. But after feedback from early users and the community, we’ve shifted our focus to working on tooling for manual database changes. We've consistently heard teams describe challenges with the way manual data updates are handled. Seemingly every engineer we spoke with had examples of errant queries that ended up causing significant harm in production environments (data loss/service interruptions). We’ve seen a few different approaches to how…
In plain words
Safe Data Changes in PostgreSQL is an open-source tool designed to help engineering teams safely execute manual database updates in production PostgreSQL environments. It addresses the risk of destructive queries by providing a structured approach to data modifications, reducing incidents of accidental data loss and service interruptions. The tool targets development teams struggling with balancing speed and safety when managing production database changes, offering a middle ground between unrestricted access and cumbersome approval processes.

Hi HN, we're excited to share our open source tool with the community! We previously posted here with the tagline “real-time events for Postgres” [0]. But after feedback from early users and the community, we’ve shifted our focus to working on tooling for manual database changes. We've consistently heard teams describe challenges with the way manual data updates are handled. Seemingly every engineer we spoke with had examples of errant queries that ended up causing significant harm in production environments (data loss/service interruptions). We’ve seen a few different approaches to how changes to production databases occur today: Option 1: all engineers have production write access (highest speed, highest risk) Option 2: one or a few engineers have write access (medium speed, high risk) Option 3: engineers request temporary access to make changes (low speed, medium risk) Option 4: all updates are checked into version control and run manually or through CI/CD (low speed, low risk) Option 5: no manual updates are made - all changes must go through an internal endpoint (lowest speed, lowest risk) Our goal is to enable high speed changes with the lowest risk possible. We’re planning to do this by providing an open-source toolkit for safeguarding databases, including the following features: - Alerts (available now): Receive notifications any time a manual change occurs - Audit History (beta): View all historical manual changes with context - Query Preview (coming soon): Preview affected rows and query plan prior to running changes - Approval Flow (coming soon): Require query review before a change can be run We’re starting with alerts. Teams can receive Slack notifications anytime an INSERT, UPDATE, or DELETE is executed from a non-application database user. While this doesn’t prevent issues from occurring, it does enable an initial level of traceability and understanding who made an update, what data was changed, and when it occurred. We’d love to hear feedback from the HN community on how you’ve seen database changes handled, pain points you’ve experienced with data change processes, or generally any feedback on our thinking and approach.

I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
