RE: Restore of a reference database kills the auto analyze processing.

Thanks for your time Adrian

> Is there enough data processing?

Yes, one table is receiving upwards of 20 million rows daily.
We noticed the problem when fetch performance on this table degraded after updates.

> Autovacuum has thresholds for turning on, are you sure those thresholds are just not being met?

Yes we're sure. Our biggest table is set for a fixed number of rows rather than a percentage, this gets an auto analyse about every 15 minutes.

After an update this just stops, and there are no analyse entries in the log file. None at all, for any table.

When we restart Postgres the auto analyse restarts and catches up with the backlog.
