Ok, now I follow.  Taking the biggest indexes:

The weekend before:

INFO:  index "message_recipients_i_recip_date" now contains 393961361 row
versions in 2435100 pages

INFO:  index "message_recipients_i_message" now contains 393934394 row
versions in 1499853 pages

After reindex:

INFO:  index "message_recipients_i_recip_date" now contains 401798357 row
versions in 1765613 pages

INFO:  index "message_recipients_i_message" now contains 401787237 row
versions in 1322974 pages
