Hi ! Is it possible in postgres to define own message for some constraint? Example: If i create check constraint on zip_code column , i want to get a message: "Zip code is invalid.Please,input code in format: nn-nnn" and I want to send this message to the end user. It will be much better(in my case) than "violates constraint zip_code_check" :-) . I can make this validation in trigger (and send msg to application by notice or raise),but in this case i will duplicate validation rules (in trigger and in constraint).Effect: Lower performance(i think) and rules in two places...
