Yep, in our load environment the table is not so big (~ 50 GB), GIN index size is ~ 1 GB. And under our load profile we have seen 90 seconds of impossibility to do an insert into the table because of vacuuming this index. I confirm that with this patch we now don’t see any spikes of errors as it was previously. -- May the force be with you… https://simply.name
