Hi all,
A while back I asked about creating a case insensitive postgresql. Tom, at the time, suggested I create a case insensitive type instead.
I am now trying to go that route, and am wondering whether domains will provide a shortcut for me. As far as I understand the task at hand, I am quite capable of using all of the existing varchar functions for input, output, storage, conversions and so on. The only thing I need to override is the comparison functions (and the resulting index creation, of course).
According to the docs, domains are not meant for that purpose, but for changing constraints of a type. Is it possible to define a domain that will have the same defaults and constraints as the base type, but will have different comparison functions? Will that provide me with what I need?
Many thanks,
Shachar
