Re: [SQL] inet/cidr - can this be done?

The problem is that host(ip)||'/24' isn't of the inet type, it's text. For
a simple select query you don't have to cast this at all, it would seem,
since it goes as text to the frontend either way.

Also, a straightforward cast inet_value::cidr seems to work for me.
