Hello, I've suscribed to this mailing list for help, I will work on a Specialization Degree Thesis, this will be a PostgreSQL implementation of fsql, or fuzzy querys.
http://www.lcc.uma.es/~ppgg/FSQL.html, this is a link to a webpage who made this in Oracle, but it's not inside of course, because it was made for other people. My work will be make this in the PostgreSQL Kernell, so i'll appreciate all help you can bring. Thanks.
