Huh, interesting!  I dug around the Berkeley archives [0] and found
comments indicating that pg_relation was renamed to pg_class in Februrary
1990.  However, it looks like the file was named pg_relation.h until
Postgres95 v0.01, which has the following comment in pg_class.h:

     *    ``pg_relation'' is being replaced by ``pg_class''.  currently
     *    we are only changing the name in the catalogs but someday the
     *    code will be changed too. -cim 2/26/90
     *    [it finally happens.  -ay 11/5/94]
