[ADMIN] VACUUM Error?

[Fabrice . Sznajderman]

Hello,


I executed a Vacuum on my Postgres database.
You can see the command line : /vacuumdb -f -z -v -d ccm > /tmp/vacuum.txt 2> /tmp/vacuumError.txt  I used  performed the vacuum.

But I had error :"ERROR:  Parent tuple was not found
vacuumdb: vacuum  ccm failed"
 each time I am executed the vacuum

have you any idea about this error? And may be any solution ?

Thanks in advance,

best regard,

Fabrice
