Hello list, ATRewriteTable in tablecmds.c uses SnapshotNow to rewrite and thus does not copy RECENTLY DEAD tuples. But copy_heap_data in cluster.c uses SnapshotAny and copys RECENTLY DEAD tuples to the new heap file.
I don't understand why it is not needed in the first case. In the second case I guess that there may be still a transaction with an older snapshot running which should be able to open the rewrited table and see the older (RECENTLY DEAD) tuple. Why must a transaction in the first case not be able to do so also?
