Ok I think this problem is not entirely fixed, my backups are failing now
with this:

pg_dump: ERROR: unexpected chunk number 5153 (expected 21) for toast value
245334402
pg_dump: SQL command to dump the contents of table "measured_bioassay_base"
failed: PQendcopy() failed.
pg_dump: Error message from server: ERROR: unexpected chunk number 5153
(expected 21) for toast value 245334402

measured_bioassay_base is always inserted at the same time as mba_data_base
(the table where I had the problem before) and it has a text field which is
very large.. I guess this is where the TOAST comes in.

Any ideas what is going on here?

Thanks again for any help

Adam
