Thanks for the patch!
I updated the patch as follows. Patch attached.
+#define XLogFileNameExtended(fname, tli, log, seg)
Move this macro to xlog_internal.h because it's used both in
pg_standby and pg_archivecleanup. There seems no need to
define it independently.
-#define MAXFNAMELEN 64
+#define MAXFNAMELEN 64
Revert this unnecessary change.
+/* Length of XLog file name */
+#define XLOG_DATA_FNAME_LEN 24
Shorten the name of this macro variable, to XLOG_FNAME_LEN,
for more code readability.
