Thank you, David.
So can i assume that autovacuum only release dead tuples when it ends its execution?
Autovacuum is not finishing and is running for days.
We did not find a parameter to limit autovacuum executing time.
Do you have any recomendation?
Thank you.
Sidney.

Hi, we have a 9.6.5 postgres
Autovacuum is set with default parameters and is running on this table for days without naping or stopping.

Its probably best avoid drawing conclusions here until the anti-wraparound vacuum has completed and you’ve updated to the latest minor version of PostgreSQL.
