export data from postgresql

I have some text like xml -code in a field of table. I want to export the data from my field into file without any changes. I've tried to use a lot of variants but all of them changes the text. The most successful variants were: COPY (SELECT alll FROM super.a_a ) TO 'D:\alll.txt' CSV ; But there appeared extra quotes "". COPY (SELECT alll FROM super.a_a ) TO 'D:\alll.txt CSV QUOTE ' ' ; But there appeared extra spaces. In my field I have such date like : name="firsname" and when I use any of varients I get something like that : name=""firstname"" or name=\n\r"firstname\n\r""
