One of the features new to PostgreSQL 9.3 is the COPY FROM PROGRAM sql construct and in psql the equivalent \copy from program. Michael Paquier covered the COPY TO/FROM PROGRAM in hist Postgres 9.3 feature highlight: COPY TO/FROM PROGRAM. Depesz covered the companion psql construction in
Support for piping copy to from an external program.
Michael demonstrated an example using curl. I wanted to try something similar using wget since I have wget readily available on all my Linux and Unix boxes. For this example I'll demonstrate doing it on windows, but doing it on Linux is much the same and simpler since the wget and curl are generally already in Linux default path.
