I am replicating a table via slony. I know the relfilenode of the table from pg_class but a new disk file is created with a different relfilenode. After the copy is complete, the relfilenode for the table is updated with the new number. Is there a way to know the "temporary" or "new" number while it is copying?
For example, table xxx is being replicated from node 1 to node 2. The relfilenode from pg_class on node 2 for table xxx is 123456. After the replication is complete, pg_class:relfilenode is updated to 234777. Is there a way to determine the relname of 234777 while it is replicating and before relfilenode is updated for table xxx? pg_class does not know about 234777 while the replication is taking place.
Any help is appreciated.
