It looks like your PostgreSQL build on Cirrus CI is failing during the
Meson configuration phase because it cannot find the libedit
libraries.
Should we add these to the pacman installation command in our CI
scripts, or is there a preferred way to handle terminal library
dependencies for the Windows Meson builds?

  1. Use AVX2 for calculating page checksums where available

  2. Refactor checksumming code to make it easier to use externally.
