Обсуждение: psql record separator

I'm trying to create a CRLF record separator using the following syntax:

psql -R "\r\n" dbname username -c "select * from foo" > data_file.txt

But, no matter what I do, it only outputs a newline (\n).  How can I
force the separator to be a windows line break (CRLF)?

According to the code, -R only affects the output in "unaligned" output
mode.  Can you use that?

I added the "-A" switch and it output the string "\r\n" instead of an
actual CRLF.

psql -A -R "\r\n" -t dbname username -c "select * from foo" > data_file.txt

I can't tell you what the proper incantation is (I didn't manage to get
it to play nice within 10 minutes), but how about a hackish solution like:
psql -A -t dbname username -c "select * from foo"|todos > data_file.txt

I got it to work by using the actual character surrounded by quotes.
That's not ideal but at least I got the line endings I needed.
