Finding relfilenode

In cost functions such as cost_seqscan, a RelOptinfo indicate a base
relation.
But there is no relfilenode in the RelOptinfo, So how could i find
relfilenode or reloid of the relation?

You could get the table OID out of the associated RTE. But I fail to
see what value the relfilenode would have at plan time.
