Hello

@@ -558,6 +584,9 @@ DropAllPreparedStatements(void)
 		/* Now we can remove the hash table entry */
 		hash_search(prepared_queries, entry->stmt_name, HASH_REMOVE, NULL);
 	}
+
+	/* Alert the client */
+	SendStmtDeallocMsg("");
 }

DropAllPreparedStatements has an early return if prepared_queries is
uninitialized, so we don't send anything in that case - but it calls
SendStmtDeallocMsg if it is initialized even when no nothing was
removed. This seems inconsistent to me, is it intentional?
