No, the \nnn escape is built into the lexer's syntax for a string literal (see backend/parser/scan.l), and only after that does the string get fed to bytea's input routine (or any other datatype's either). In hindsight this was a horribly bad idea that we'll be paying through the nose for, for some time to come :-(. But we're stuck with it for the moment. regards, tom lane
