Okay. 
I change to the following messages.

/* 
 * The bgwriter writes WAL of FPW at checkpoint. But does not at shutdown.
 * Because XLogReportParameters() is always called at the end of startup
 * process, it does not need to be called at shutdown.
 */


In addition, I change macro name.

REPORT_ON_BACKEND -> REPORT_ON_BGWRITER
