RE: Assertion failure in GetSubscriptionRelations() with concurrent DROP TABLE

[Hayato Kuroda (Fujitsu)]

Dear Vignesh,

Thanks for updating the patch. I confirmed it could fix the issue.


```
+               else
+                       elog(ERROR, "unexpected relkind: %d", (int) relkind);
```


I feel \"%c\" might be better than %d, like what ProcessUtilitySlow() does,
because the relkind is defined as char.

Best regards,
