Hmm, comparing gin_desc() to ginRedoInsert() makes me think there are more
problems there than that one. Aren't the references to "payload" wrong
in all three branches of that "if" construct, not just the middle one?
I'm inclined to suspect we should restructure this more like
{ ginxlogInsert *xlrec = (ginxlogInsert *) rec;
- char *payload = rec + sizeof(ginxlogInsert);
appendStringInfo(buf, "isdata: %c isleaf: %c", (xlrec->flags &
GIN_INSERT_ISDATA)? 'T' : 'F', (xlrec->flags & GIN_INSERT_ISLEAF) ? 'T' : 'F');
if (!(xlrec->flags & GIN_INSERT_ISLEAF)) {
+ char *payload = rec + sizeof(ginxlogInsert); BlockNumber leftChildBlkno;
BlockNumber rightChildBlkno;
leftChildBlkno = BlockIdGetBlockNumber((BlockId) payload); payload +=
sizeof(BlockIdData); rightChildBlkno = BlockIdGetBlockNumber((BlockId) payload);
payload+= sizeof(BlockNumber); appendStringInfo(buf, " children: %u/%u",
leftChildBlkno, rightChildBlkno); }
+ if (XLogRecHasBlockImage(record, 0))
+ appendStringInfoString(buf, " (full page image)");
+ else
+ {
+ char *payload = XLogRecGetBlockData(record, 0, NULL);
+ if (!(xlrec->flags & GIN_INSERT_ISDATA)) appendStringInfo(buf, " isdelete:
%c", (((ginxlogInsertEntry *) payload)->isDelete) ? 'T' : 'F'); ... etc etc ...
