db fall back to users file

[Angelos Karageorgiou]

A good one for you ,

when using an rlm_sql module if the sql server is down the module fails 
to instantiate and FR does not start at all.
Is there  a way to force instantation of rml_sql no matter the status of 
the sql server.

Specifically I am trying to do


redundant { 
    sql
    fastusers
}


the idea is to switch to a local file when the db is down.

On a second thought can I do ?

accounting {
    redundat {
        sql
        detail
    }

}
