Hi  Team

Can we generate a fill factor for tables that have delete ops ?

Does the fill factor really work and help to minimize the bloat for tables that have delete ops?

I have parent table with weekly partitions So for every week 50 to 60 gb of bloat generates and autovacuum params already in place for child tables 

This confuses me.  It seems that you are deleting old data instead of just dropping the old partitions.

What did I misunderstand?

Hi 

I have partitioned table with retention policy of 90 days and will be auto purged partitions beyond 90 days and  for last 90 days tables inserts and deletes usually run through apl call 
Here due to deletes ops on last 90 days weekly partitions bloat generates 50gb to 60gb for on weekly partition even we set autovacuum params already in place for at child tables level
