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 Regards. -------------------------------------------- Jun Ishizuka NTT Software Corporation TEL:045-317-7018 E-Mail: ishizuka....@po.ntts.co.jp -------------------------------------------- -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
