Hi
Thanks for the help but this will not help, killing other process is not safe
The good way will be that pg_repack tools include a timeout so, that after expiration delay, he will stop waiting and
discardthe repack action
But thanks again for your proposition.
Regards,
Nicolas

Allow it to kill offending backends after some time? For example -T 7200?
