Investigate more:
- Make sure that you don't get files from another filenode like 3276838.
- If the relation (as shown by pg_relation_size('tablename')) is 73GB,
it should consist of 327683, 327683.1, 327683.2, ..., 327683.72.
Check what additional files there are.
- Extra files can be left behind after a crash. Were there any?
