Thanks for updating the patch!
As I suggested in the reply to Simon, I think that the change of FPW
should be WAL-logged separately from that of HS parameters. ISTM
packing them in one WAL record makes XLogReportParameters()
quite confusing. Thought?
if (!shutdown && XLogStandbyInfoActive())
+ { LogStandbySnapshot(&checkPoint.oldestActiveXid, &checkPoint.nextXid);
+ XLogReportParameters(REPORT_ON_BACKEND);
+ }
Why doesn't the change of FPW need to be WAL-logged when
shutdown checkpoint is performed? It's helpful to add the comment
explaining why.
