actually, its a big application with many sql messages, and removing "ERROR:" keyword from the message after SQLException is caught is the last resort. on debugging, I find that thetoString() method ofServerErrorMessage class creates the final message. I was just thinking if there is a way to intercept this method call and make some changes. I am using Java and Jdbc. Below is the method fromorg.postgresql.util.PSQLException which calls thetoString()

public PSQLException(ServerErrorMessage serverError, boolean detail) {        super(detail ? serverError.toString() : serverError.getNonSensitiveErrorMessage(), serverError.getSQLState());        this.serverError = serverError;    }
