- * rd_firstRelfilenodeSubid denotes would restore rd_node to the value it
- * had at the start of the current top transaction. Rolling back any
- * lower subtransaction would not.) Their accuracy is critical to

- * rd_newRelfilenodeSubid is the ID of the highest subtransaction the
- * most-recent relfilenode change has survived into or zero if not changed
- * in the current transaction (or we have forgotten changing it). This
- * field is accurate when non-zero, but it can be zero when a relation has
- * multiple new relfilenodes within a single transaction, with one of them
- * occurring in a subsequently aborted subtransaction, e.g.
+ * survived into; or zero if the rel was not created in the current top
+ * transaction. This can be now be relied on, whereas previously it could
+ * be "forgotten" in earlier releases. Likewise, rd_newRelfilenodeSubid is
+ * the ID of the highest subtransaction the relfilenode change has
+ * survived into, or zero if not changed in the current transaction (or we
+ * have forgotten changing it). rd_newRelfilenodeSubid can be forgotten

+ * subtransaction, e.g.
