Is it possible to turn off quote processing in the Postgres COPY command with CSV format?

Question

I have CSV files, tab-separated, fields not wrapped in quotes, where field data can contain characters like single quotes, double quotes, pipes and backslashes.

For the record, since I've been struggling with the same issue, you can use tr to remove \b, instead of just hoping it's not in your text anywhere.

tr -d '\010' < filename.csv > newfile.csv

(Using that \010 is the octal representation of \b).

Since COPY supports reading from STDIN, you can ease the I/O impact by piping tr's output:

cat filename.csv | tr -d '\010' | COPY  FROM STDIN WITH CSV DELIMITER E'\t' QUOTE E'\b' NULL AS '';
