That sounds bad, but most parameters apply to one or the other, not both. If there are some that apply to both, then yes, coordination would be important. It does seem likely that the new scheme will require us to look carefully at when parameters are reloaded, since the timing of reloads was never taken into account in the previous coding. -- Simon Riggs http://www.2ndQuadrant.com/ <http://www.2ndquadrant.com/> PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
