I tried to do a manual vacuum today after purging over a million hands but it returns an error message repeatedly. When trying to vacuum using the HEM database management tool i get the same message which reads 'ERROR:XX000 could not read block 59441 of relation base/16397/16620: Invalid argument'.
If i try to do a DB reindex i get a similar message. Is there anything i can do since I want to reclaim the space as I will be moving it to an SSD fairly soon where space is at a premium.
Thanks
