Agreed.

Ah, that sound good.

     if (!entry_ref)
+    {
         entry_ref = pgstat_fetch_pending_entry(PGSTAT_KIND_RELATION, InvalidOid, rel_id);
+        return tablestatus;
+    }

We should return something if the call returns a non-null value?

So, since we want to hide the internal from pgstatfuncs, the
additional flag should be gone. If the additional cost doesn't bother
anyone, I don't mind to remove the flag.  The patch will get far
simpler by that.

regards.
