I\'m using PGAdmin 1.14.3.
When I try to execute an import command:
COPY grad(country_code, postal_code, place_name, admin_name1, admin_code1, admin_
To solve this problem you must give permission to the CSV file because that CSV file present in a COPY command are read directly by the server, but not client application. So to make this file accessible to a server we must give full read-write permission so that Postgresql user can read and write on that file.
