Just for the record, the 16384 is the OID of a database (look at
pg_database.oid) and 2613 is the filenode of a table (look at
pg_class.relfilenode in the relevant database). contrib/oid2name
can help mechanize this but personally I never bother with that.
See http://www.postgresql.org/docs/9.2/static/storage.html
for the authoritative skinny (but note this stuff does change
across releases, so be sure to read the correct version of the docs).
