I have a hard time believing that adding a strlen() to the handling of a short column won't be a measurable overhead with lots of short attributes. Particularly because the patch afaict will call it repeatedly if there are any to-be-escaped characters. I also don't think it's good how much code this repeats. I think you'd have to start with preparatory moving the exiting code into static inline helper functions and then introduce SIMD into those. Greetings, Andres Freund
