I've got a problem with my postgresql database 9.4 this morning.
Few days ago we've moved many data in the database to create new data partitions and delete many entries.
Auto-vacuum seems to be inefficient and i am unable to vacuum my zabbix database.
Do you have any idea about this problem ?

Why are you unable to VACUUM your zabbix database? because it is the solution to your issue.
