This certainly did not work in 7.3 (in fact, you are quoting the 7.3
spelling of the error message).
There is not and never has been a LIKE operator for inet values; it's
only defined for textual data types. The reason it "worked" in 7.2 was
that 7.2 would implicitly cast the inet value to text for you. In 7.3
we changed a lot of casts to not be implicitly invocable, because of the
potential for unexpected behavior. Personally I'd class this as an
example of exactly the kind of unexpected behavior we meant to
Short anser: cast the field value to text.
