I don't quite see how this is supposed to work:
+ #ifdef WAL_DEBUG
+ /*
+ * If xlog debug is enabled then check produced delta. Result of delta
+ * application to saved image should be the same as current page state.
+ */
+ if (XLOG_DEBUG)
+ {
+ char tmp[BLCKSZ];
+ memcpy(tmp, image, BLCKSZ);
+ applyPageRedo(tmp, pageData->data, pageData->dataLen);
+ elog(ERROR, "result of generic xlog apply doesn't match");
+ }
+ #endif
I suppose the elog(ERROR) call should be conditional ...
