Hello Jon,

thank you for your reply; everything went well during our migration. We 
saved the PG9 databases using pg_dump from PG13 and restored them 
accordingly within the new system. Afterwards a 'bucardo upgrade' did 
the job.

The verbose level is maybe a matter of taste, but no problem :)

Again, thank you for your help and I wish you all the best
