HelloBonsoir,

Which operating system are you dealing with on the client side?

For this kind of purpose, I have a handy script which does the job 
flawlessly, I've never had problems with any wéird frènch âccènts.

I don't use the \c command, but the COPY TO syntax, rather.  I can't 
remember the reason why, but it just works.


Here's the complete script:

   # pierre@latitude: ~        < 2017_11_23__19_07_35 >
cat bin/sql2csv
#!/bin/sh
# (c) Pierre Chevalier
# Ce script fait un fichier csv à partir de la bd postgresql GLL_BD_NAME 
dans l'hôte GLL_BD_HOST, avec la requête en entrée
# This script creates a csv file from the postgresql database 
GLL_BD_NAME served by GLL_BD_HOST host, with the query specified as a 
double-quoted string input
#$1: requete
#$2: fichier de sortie .csv => bof, non, on redirige, plutôt
#$1: query
#$2: .csv output file       => bof, no, better to just redirect or pipe, 
later
echo "COPY ($1) TO stdout WITH CSV HEADER FORCE QUOTE *" | psql -X -h 
$GLL_BD_HOST $GLL_BD_NAME


As you can see, only the last line is relevant.  I use the script as 
follows, after adjusting the variables are set properly:


   # pierre@latitude: ~        < 2017_11_23__19_07_35 >
sql2csv "SELECT DISTINCT opid, year FROM public.field_observations ORDER 
BY year LIMIT 10" > /tmp/rien.csv

   # pierre@latitude: ~        < 2017_11_23__19_07_35 >
cat /tmp/rien.csv
opid,year
"0","1946"
"0","1997"
"9","1997"
"0","1998"
"9","1998"
"9","1999"
"0","1999"
"9","2000"
"17","2000"
,"2006"

   # pierre@latitude: ~        < 2017_11_23__19_07_35 >


I'm doing this on Debian GNU/Linux, both on client and server.


In your case, you could try something like this (on one line):

echo "COPY (SELECT * FROM t1) TO stdout WITH CSV HEADER FORCE QUOTE *" | 
psql -h db1 -U u1   -d d1 > test.csv
