Hi, I agree, pgloader seems to be right. And yes, it’s a matter of complexity and usability estimation. Stefan

Why not the ability to restrict lines too COPY stafflist (userid, username, staffid) FROM 'myfile.txt' WITH (FORMAT text, DELIMITER E'\t', COLUMNS (1, 2, 7), LINES(2:1000,2000:3000), ENCODING 'windows-1250') => subset of full data. At some level of complexity it is questionable whether a feature belongs in core that can exist outside of it. While I have not yet personally used pgloader it seems to accomplish much of what is being requested. http://pgloader.io/index.html COPY (and \copy) serves its purpose extremely well but expects the user to deal with any customization needed either before or after it has done its thing. I believe this is for the best since such customizations and tools have no need to operate on the same release cycle as the core PostgreSQL project. David J.
