Hi,

Would it be possible to add support for the Redshift HEADER option to the UNLOAD statement?

The HEADER option adds a CSV header (the query column names) to the output CSV file.

Thanks,
Danijel

FYI, I'm working on this feature now, planning to raise a Pull Request soon.

…the IGNOREHEADER option in the COPY command

As per the official Redshift docs (https://docs.aws.amazon.com/redshift/latest/dg/r_UNLOAD.html), the
HEADER options enables Redshift to add the header (column names) to the CSV files produced by the
UNLOAD command.

Similarly, as per the official COPY command docs (https://docs.aws.amazon.com/redshift/latest/dg/r_COPY.html),
the IGNOREHEADER option enables Redshift to skip the first N lines in the input CSV file (ie. the CSV
header).

This feature is REALLY welcome and needed because in my Team we need to simulate the output of a query run containing headers, as is returned by real Redshift. It's an amazing addition to the driver. Thanks so much @dschiavu !!
