Обсуждение: Bug #670: netmask displayed for a /32

Edwin Groothuis (edwin@mavetju.org) reports a bug with a severity of 3
The lower the number the more severe it is.

Short Description
netmask displayed for a /32

Long Description
The documentation says (chapter 3.8.1):
The input format for this type is x.x.x.x/y where x.x.x.x is an IP address and y is the number of bits in the netmask.
Ifthe /y part is left off, then the netmask is 32, and the value represents just a single host. On display, the /y
portionis suppressed if the netmask is 32. 

This works fine in this case:
pmoanalysis=> select ipaddress from dhcpservers;
 ipaddress
-----------
 1.2.3.4
(1 row)

But the /y portion is shown in this case:
pmoanalysis=> select ipaddress||'a' from dhcpservers;
  ?column?
-------------
 1.2.3.4/32a
(1 row)

I'm running pgsql version 7.2 under FreeBSD

This implicitly coerces the inet value to text datatype, and the
text(inet) function always displays netmask.  Perhaps you'd prefer
to use host() or abbrev() to do the conversion to text.

I've already changed it to use host(), was just a message to let
you know that it might not have been working the way you expected
it to do.

Thanks for your reply and the database, it rocks :-)
