Hi All,
I'd be happy to submit a patch if this sounds like a desirable feature, but I'm not really clear on the right place / people to start the discussion. I'd appreciate any pointers people have as to 'the right forum' for this.
I've frequently seen an issue in applications which store titles (eg of books, events, user profiles) where duplicate values are not properly vetted.
The 'citext' type is helpful here, but I'd be keen to go further.
I propose a 'titletext' type, which has the following properties when compared for equality:
* Case insensitivity (like 'citext')
* Only considers characters in [:alnum:] (that is, ignores spaces, punctuation, etc)
This would be useful for a range of situations where it's important to avoid entering duplicate values.
Thanks,
Daniel Heath
