When a relfilenode is created in this subtransaction or a committed child transaction and it cannot otherwise be seen by our own process, mark tuples committed ahead of transaction commit for all COPY commands in same transaction. If FREEZE specified on COPY and pre-conditions met then rows will also be frozen. Both options designed to avoid revisiting rows after commit, increasing performance of subsequent commands after data load and upgrade. pg_restore changes later.
