Well, PG's files are named after the OID of the sytem object
(database/table/index) they hold. You can look this up in the system tables
or there is an oid2name tool in the contrib/ directory of the source distro.

You will also want to read Ch11 in the Administrator's guide.

You might want to try a VACUUM FULL of the table, and perhaps REINDEX to
reclaim any unused space.
