To me this seems pretty clear: indexes are not automatically inherited 
and the master table is usually empty => index child tables.  It's all 
in the docs:

http://www.postgresql.org/docs/8.1/static/ddl-inherit.html#DDL-INHERIT-CAVEATS
http://www.postgresql.org/docs/8.1/static/ddl-partitioning.html
