To find the table name to file mapping in a database:

  SELECT relname, relfilenode
    FROM pg_class
    ORDER BY relname;

relfilenode seems to be the same as the table's oid, but there must be
circumstances where that is not the case.


To find the mapping of databases to the numbers under ${PGDATA}/base:

  SELECT datname, oid
    FROM pg_database
    ORDER BY datname;

     "Love is patient, love is kind. It does not envy, it
      does not boast, it is not proud. It is not rude, it is
      not self seeking, it is not easily angered, it keeps
      no record of wrongs. Love does not delight in evil but
      rejoices with the truth. It always protects, always
      trusts, always hopes, always perseveres."
