Make a note now of the table's "relfilenode" value (it'll be different
in each database), and confirm that you see it in the filesystem. After
the next disappearance, see if anything's still there. For background
read
http://www.postgresql.org/docs/8.2/static/storage.html
Note that certain operations like TRUNCATE and CLUSTER change the
relfilenode, so if you're using any of those then it might get harder to
track where the file is.
