> I would like to propose that we expose the "active" value of parameters in pg_settings, instead of "-1".  In this
examplebelow, when it's set to "-1" I need to know that autovacuum_work_mem is related to the setting of
maintenance_work_mem,so that I can determine that the actual setting is 64MB: 

If we did that, how would you tell the difference between "-1" and a hard
setting of 64MB?
