@@ -2036,8 +2035,8 @@ RestoreBlockImage(XLogReaderState *record, uint8
block_id, char *page)
  char    *ptr;
  PGAlignedBlock tmp;

- if (block_id > record->record->max_block_id ||
- !record->record->blocks[block_id].in_use)
+ if (block_id > XLogRecMaxBlockId(record) ||
+ !XLogRecGetBlock(record, block_id)->in_use)

I thought these can also be rewrite to:

if (!XLogRecHasBlockRef(record, block_id))
