Could you please let us know if you have analyzed after the re-indexing is done ?
This must show differences for only Indexes not the Tables.
For Tables, you need to do VACUUM FULL to show the difference.
Thanks

Using the query http://wiki.postgresql.org/wiki/Show_database_bloat, I got the following result for a table:

tbloat | 0.9

-[ RECORD 3 ]----+-----------------------------------------------
current_database | crm
schemaname | public
tablename | _attachments
tbloat | 0.9
wastedbytes | 0
iname | _attachments_pkey
ibloat | 0.2
wastedibytes | 0
I REINDEXED both the indexes and table, but I did not find any change in wastedspace or wastedispace.
Could you please tell me why?
