index's relpages after table analyzed

After a table analyzed a table, the table's relpages 
of pg_class gets updated, but not those of associated 
indexes, which can be updated by "vacuum analyze".

Is this a feature or a bug?

I have some tables and there are almost only
inserts. So I do not care about the "dead tuples",
but do care about the statistics. 

Does the above "future/bug" affect the performance?

My PG version is 7.3.2.
