According to the error message, the problem happens during reading
pg_database. I just tried to plug in this line in mdread():

+        /* pretend there is an error reading pg_database */
+        if (reln->smgr_rnode.relNode == 1262)
+        {
+                fprintf(stderr, "Ooops \n");
+                return false;
+        }
       v = _mdfd_getseg(reln, blocknum, false);

And it works.
