Do you work alone by chance? Because it's pretty easy to avoid problems when you work alone, remember what exactly the code does. However, when working even in a small team (3-5 devs), it's becoming much harder to avoid such footg

A more complex plan isn't already more expensive in a way that captures how much work the JIT will need to do. I think I'll need to write a separate blog post about that, with details and examples.

I'm not sure I can, and I definitely do not want to do that. I'm happy with a separate table and `btree` index on it.

I have thought about expression indexes, and for expressions I need (@> on jsonb) they can't be used.

What I called complexity is an amount of different nodes (not sure this is the proper term) in a query plan. So, the more complexity for a given cost - the more work JIT needs to do.

It's enabled by default since Postgres 12, and in some cases can be harmful, I mentioned it in my blog post about JSONB indexes [1]. I found it hard to make Postgres reuse JIT-compiled plans, and quite often JIT compilation can kick in

Thank you very much, I use screen rarely and the thought that screen can be configured has never crossed my brain.

Well, Android site says that it supports UVC cameras over USB, so presumably you get this feature for free!

Would you buy a webcam with 1080p only (I promise it's good though!) for $250-$300?

Yes, optical depth-of-field is only possible with reasonably big sensor sizes and wide-open lens. Reportedly, Huawei P40 Pro has an IMX700 sensor with the 1/1.33" diagonal. I didn't run the numbers for it, but it is big enoug

I agree that we should distinguish quantity and quality. If we don't have enough light in a scene, we need to raise ISO for a given camera and that can easily make scene look bad. For other camera with bigger and less noisier sensor, b

It seems I needed to include a couple of shots - one is from my laptop webcam, and the other is from my phone. What "bad lighting" is changes very much based on the camera capabilities (lens, sensor, post-processing).

You actually want a mirrorless camera, not a DSLR one. If you intend to only use it as a webcam, probably just buy Panasonic G7 or Canon M200 for $500.
