The problem is that I have hard-coded 8k into various text strings and I
didn't want to make that variable. How should it behave if they are
using a non-8k wal buffer size? Should it still use 8k or not? I
figured throwing an error would at least alert them to the mismatch.
Good point on the build problem --- I had not thought of that. Throwing
an error when running makes more sense, but let's figure out what it
should do.
