Check if you can group them in a subnet that will not be user for other
purposes...

AFAIK it just requires a reload, without restarting server (using a
subnet you have to do it less frequently, however)

If I were you, in a production environment I'd *never* use trust level,
even for localhost.
the best thing that comes in my mind is to set a subnet where all
servers (and no one else) will reside and combine it with users, like this
host all user1 192.168.1.0/32 md5
host all user2 192.168.1.0/32 md5
host all user3 192.168.1.0/32 md5
...
and so on.
Best regards,
Moreno
