I've now done this for the Scheduler of one application.  Early on, things 
look good, but I picked the app where a miss by the scheduler wouldn't be 
too painful.

It seems I had to remove the old scheduler tables, as well, to help with 
the migration.
 
Now I've got a new question:  If 2 apps are scheduling, and both are using 
Postgres, are they both using the same table?  
>From psql, it doesn't look like there's anything in the table creation to 
isolate it from other applications (that is, \dS scheduler_task doesn't 
show anything to uniquify the table, but there is an "application_name" 
field, and then the select * for a sample task has app1/default in that 
field).

Will Auth also be shared?  The .schema auth_user doesn't have 
application_name.

See other thread, but it seems to an issue of where the DAL looks for the 
driver, and I've gotten it wrong so far.

Thanks
