I posted about this previously:

http://article.gmane.org/gmane.comp.bacula.user/16853/match=pragma

Looks like they just removed the option to default all databases to
non-synchronous operation in SQLite 3.0, requiring you to manually set
your databases to be asynchronous. A good decision, I would say.

I think the 'default_synchronous' setting will only apply to databases
when they're created (or, to put it another way, changing it will not
affect any existing databases).

Since you're taking backups of the database, and you can restore the
catalog by using bscan, I don't see the need for synchronous operation,
unless you absolutely cannot have your database server down for the time
it would take to restore the catalog in the event of a power failure or
somesuch.

I'll be turning it off tonight, to see what difference it makes to
performance...
