Not necessarily --- the filename is initially the same as the index OID,
but it wouldn't be anymore after a REINDEX. Instead use what you get from
select relfilenode from pg_class where relname = 'page_view_visit_idx';
and note you will need to recheck it after reindexing.
Also, it's a good idea to do CHECKPOINT right before copying the
physical file, to make sure you've got a consistent file image on-disk.
If you want to be 100% certain, shut down the postmaster while copying,
but unless the index file is pretty large I think that's not necessary.
