Thanks, upgraded database to version 11 and dir/sd/fd 2.4.3 on server to  
3.0.3,
left other clients on 2.4.4, so far everything working fine.

Will probably do the same to 5.0.2 next week and then look at upgrading
clients.

configure turned out to be easier :) As before with 2.4.3 I just can't get
readline instead of conio compiled into bconsole, but it's not a huge loss.

That would not be very nice in the middle of an emergency when it's needed
most urgently. Is there a standardized way to crossgrade to postgres
without losing all your current backups? I need to upgrade since staying
with 3.x would mean that new installations with newer clients in their
repos would need to be downgraded and that outside their regular packaging
systems too.

I suppose you would need to install the pgsql packages, configure and make
Bacula for postgres and run some convert db script before using make
install?
