Originally RST split up data frames and wrote out CSVs as temp files to then reload the data and read it in as raw bytes. I use readr's format_csv to create a "csv" in a string that can be converted to bytes directly in RAM.
This created a problem where POSIXCT timestamps get written into the csv-string with utc timezone in the format and now redshift won't load those columns.
