RE: How can i be certain autovacuum is causing reuse if table still grows

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.
