This seems like the most likely cause. I would guess that one of your
GiST indexes has a corruption in it and is preventing a restartpoint
from taking place. That has happened previously.


You're right.

On the master, we had an error about a gist index on a ltree column :

Aug 25 09:07:02 eurovox-bdd postgres[5575]: [18-1] user=eurovox,db=eurovox_db PANIC: failed to add item to index page in "appels_entrants_arbo_key"

The cluster try to restart ( it fail ), i had to force to stop.

Since this moment, the slave didn't make any checkpoint.

Now, we know why. Thanks a lot !

But how can i fix it ?
