Hoe een gezipt bestand in Postgres Table te importeren

Vanuit Postgres:

COPY table_name FROM PROGRAM 'unzip -p input.csv.zip' DELIMITER ',';

Van de man-pagina voor unzip -p :

-p     extract files to pipe (stdout).  Nothing but the file data is sent to stdout, and the files are always extracted  in  binary
       format, just as they are stored (no conversions).
