Обсуждение: BUG #17841: COPY Command Invalid QUOTES

The following bug has been logged on the website:

Bug reference:      17841
Logged by:          Stefan Goldener
Email address:      stefan.goldener@theprosperity.company
PostgreSQL version: 11.16
Operating system:   x86_64-pc-linux-gnu
Description:

The COPY command doesn't quote properly e.g.:

COPY (SELECT *, CURRENT_DATE as partitiondate FROM {table}) TO STDOUT WITH
(DELIMITER '|', QUOTE '\"', FORCE_QUOTE *, FORMAT CSV, HEADER)

delivers:
faasdfagdf|"1234"||
as output

so the first column is not quoted properly

Hm, I failed to duplicate that here, and the relevant code looks
pretty straightforward.  Can you give a more concrete example?
Is this server unmodified community Postgres?  (The fact that it's
taking QUOTE '\"' without complaint indicates that you're at least
running with some nondefault settings.)
