Hey hey, post author here.

This is a really good point that wasn't fully clear to me - this post definitely focuses on the \COPY from psql, rather than the CopyFrom backend.

I've gone ahead updated the post in the introduction to highlight that this post is about `psql`. My goal here is to try and understand Postgres better - so thank you for pointing this out :). I think writing a future post going into the backend code you mentioned is necessary. My goal is to have solid reasoning on why `COPY` is faster, and I'll need to keep writing these posts to get there.

Let me know if you think it's still unclear - I don't want to leave up any article that's potentially confusing.

I've also cleaned up the language a bit around `libpq`, I mistakenly restated the description of `libpq` from the Postgres , which is stated as "libpq is the C application programmer's interface to PostgreSQL. libpq is a set of library functions that allow client programs to pass queries to the PostgreSQL backend server and to receive the results of these queries.", but you two are correct, my statement was confusing.
