If you want to create that file on the client machine, you'll have to select and fetch it like any other value, then open a file and write the contents into it. If the bytea is large, you could select parts of it (with the substring() function) and thus do it in pieces. For some APIs, you could also use COPY TO STDOUT. Details depend on the API and programming language you are using.
