Hi everyone
I changed my mail account to be officially displayed in the correspondence.
I also made an error conclusion if we are given an incorrect value. I
believe that such a cast is needed by PostgreSQL since we already have
several incomplete casts, but they perform their duties well and help in
the right situations.
