(I'm afraid that this thread is not for the discussion of the patch?:)

+/* printf/elog format compatible with 32 and 64 bit xid. */
+typedef unsigned long long             XID_TYPE;
...
+        errmsg_internal("found multixact %llu from before relminmxid %llu",
+                        (XID_TYPE) multi, (XID_TYPE) relminmxid)));

"(XID_TYPE) x" is actually equivalent to "(long long) x" here, but the
point here is "%llu in format string accepts (long long)" so we should
use literally (or bare) (long long) and the maybe-all precedents does
that.

And.. You looks like applying the change to some inappropriate places?

-      elog(DEBUG2, "deleted page from block %u has safexid %u",
-         blkno, opaque->btpo_level);
+      elog(DEBUG2, "deleted page from block %u has safexid %llu",
+         blkno, (XID_TYPE) opaque->btpo_level);

regards.
