[Box Backup] postexec

[Peter Huber]

I have installed boxbackup on a linux server to backup openbsd server. 
Till now everything works fine, but I want to backup an postgresql 
database. There a two ways of doing it: First pgdump and second stop the 
database and backup. With the first way it is impossible to do in 
incremental backup what could be a problem in our installation. So I want 
to stop the database backup and start the db again. My problem now is, 
that bbackupctl always returns immediately. Is it possible to get any 
signal after the client has finished the backup so that I can restart the 
postgresql-db ?
Thanks
Peter
