How bad could it be?

Well, as long as it is well documented...I'm sure it will be fine. (as I am not that one that will have to maintain it)

throws it on the giant pile

At this moment, I am staring at a 200-line block of postgresql that has about 40 JOIN clauses. It is not trivially or realistically debugable, testable, or extensible by anyone, including the people who wrote it (and no, I didn’t write this shitshow). There are basically zero nuanced tests around it, despite the fact that that’s a banner I’ve carried in a pretty militant fashion since starting at this place about 2.5 years ago, meaning that I trust this baroque confluence of relational db logic about as far as I can throw my car. It was done this way because “we’ll have time to go back and optimize it later (oh, sweet summer child)”.

I’m slowly going insane.

People try to be overachievers by exceeding expectations and then are often late or delivering a broken product.

It's hard to tell perfectionists not to be perfectionists though.
