bf_compact leaving possibly huge backup

[Boris 'pi' Piwinger]

Hi!

bf_compact does create a backup of the old database. This
certainly is useful, but it might cause serious problems if
the quota is tight.

I understand (hopefully correctly;-) that to compact we need
to generate a new copy of the database. So the quota must be
sufficient to do that. There is probably no way around that.

But in the end it would help to not have backup if unwanted.
So an option to not keep a backup would be much appreciated.
