Well, we certainly *could*, but what's the use-case really?  The case
for varying BLCKSZ is marginal already, and I've seen none at all for
varying XLOG_BLCKSZ.  Why do we need to make it easier than "edit

The use case I could see is for performance testing but I would concur that it doesn't take much to modify pg_config_manual.h. In thinking about it, this might actually be a foot gun. You have a new pg guy, download source and think to himself..., "Hey I have a 4k block size as formatted on my hard disk". Then all of a sudden they have an incompatible PostgreSQL with everything else.
