“Invader Now” (Fumihiro Nonomura)
The approach presented here isn’t revolutionary, nor did I invent it. Preparing this paper was more about connecting the dots, polishing patterns, and providing a practical example of how it can be used. Sadly, this design is relatively unknown (especially when compared to the alternatives), and what’s worse, it seems nameless. So I decided to call it a “Module Infrastructure-Module Application Architecture” or just MIM for short.

JIT compilation was introduced in Postgres 11 in 2018. It solves a problem of Postgres having to interpret expressions and use inefficient per-row loops in run-time in order to do internal data conversions (so-called tuple deforming).
You should generally not try to recover these errors. It’s okay to explode—crash, panic, and throw.
