Thanks! Patch attached.
Since they are located just before wal_buffers in postgresql.conf.sample,
I moved the descriptions of them also just before that of wal_buffers
in "Write Ahead Log"/"Settings" section.
BTW, while reading guc.c, I found the GUC context of wal_recycle is
PGC_SUSET. But isn't it better to set it to PGC_SIGHUP because wal_recycle
doesn't affect any backends? Basically checkpointer and startup process
use wal_recycle.
