I'm now thinking maybe the compilation options for PG 17.5 have been different. I'm using the default version that comes with Homebrew, but for PG 18, I compiled it myself. Here are the results for `select version();` on both:

PostgreSQL 17.5 (Homebrew) on aarch64-apple-darwin24.4.0, 
compiled by Apple clang version 17.0.0 (clang-1700.0.13.3), 64-bit

In my tests I build from source from both the 17 stable and head branch 
and use the same build options. 

Why temp uses checksum, which also happens on 17 and presumably 
earlier versions, is still not too clear to me.
