It’s about the time for year-end performance reviews. While I’m always afraid I’ll narrowly avoid being fired for gross incompetence, that’s not usually how it goes. But that meeting did remind me about a bit of restructuring I plan to impose for 2017 that should vastly improve database availability across our organization. Many of the techniques to accomplish that—while Postgres tools in our case—are not Postgres-specific concepts.
One of the best features Postgres boasts is the ability to adapt. Any schmo off the street can write an extension and bolt it onto Postgres with nary a second glance. As proof, I’m going to whip one up really quick. That should be enough to convince anyone that it takes no skill at all to add functionality to Postgres.

It has the utterly impossible mission of converting our ridiculous and inane requests into a logical series of fetch, filter, sort, join, and other instructions. Then the resulting steps must be ruthlessly efficient or the execution phase could very well saturate every hardware resource available; Set Theory isn’t very forgiving.
The United States held an election recently, and there has been some … mild controversy regarding the results. Many raised issues about this before the election itself, but what if we had used instant-runoff voting instead? More importantly, can we implement it with Postgres?
Through the wonderful magic of corporate agreements, I’ve been pulled back into (hopefully temporarily) managing a small army of MySQL servers. No! Why can’t this just be a terrible nightmare?! Does anyone deserve such debasement?
Side effects of using MySQL may include…
