That is another point that has me confused.
I have been testing to make certain changes I have made to the access file
were really there with postmap -q.

With the movement of IP addresses and CIDR blocks out of the access
file and into a "cidr-ip" file postmap -q would find them in the
cidr-ip.db file.
If I remove the .db ile (As Noel points out not necessary) then I get
an error because postmap seems to only look in database files:

$ postmap -q 222.254.228.0/24 cidr-ip
postmap: fatal: open database cidr-ip.db: No such file or directory

As I originally posted: "An strace of "postmap -q <any-pattern>
cidr-ip" shows it is the cidr-ip.db file that is being read." by
postmap.
