i have been playing with the inet and cidr types, and i have noticed a couple
problems, and would entertain suggestions as to how to fix them without
necessarily breaking how other people might be using them.
- a table with an element of type inet, will show "0.0.0.0/0" as "00/0"
i suspect this can be fixed in src/backend/adt/network.c or some such.
- when creating a table with either type inet or type cidr as a primary, unique
key, the elements "198.68.123.0/24" and "198.68.123.0/27" are considered
equal.
i considered editing src/backend/adt/network.c and changing the various
comparison functions to take the subnet bits into account, but i wasn't sure
what the proper fix is.
my feeling is to make "/27" to be greater than "/24", such that when fetching
in order, the "/24" will come first.
if i make such changes to the source, will it break other people's code if
the changes get added to the core source (6.4.3 or 6.5)?
