Ok, minor confusion here.
The AOLserver CVS nspostgres has the new DbFail() routine (as mentioned in the previously referenced thread), but does not have Randy Kunkee's patch (for the exception code) in it.
Is the version you have different from the current AOLserver CVS version?
Or is this a different 'CVS' here? Would you mind clarifying there so that I can make sure that the nspostgres in AOLserver CVS is actually 'correct'? Being that I'm the maintainer of that code it'd be nice to know.
