In the following output the vacuum knows there are 99,612 pages and 1,303,891 rows. However the last line of output during the analyze only thinks there are 213,627 rows. Is this so far off because the table is bloated? Version of PostgreSQL is “PostgreSQL 7.4.3 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2.2”
