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
