PostgreSQL: import several .csv files through sql copy statement
Now, since the server administrator are being a little privy of their server, they would like to give us access only to the SQL server and not to the underlying unix server.


I'm not sure how you're accessing the SQL server from that. However, if you're going to keep getting access to psql, perhaps you can work around their security with \! in psql

  \! [COMMAND]           execute command in shell or start interactive shell
