Hello
I have found a solution for my second problem.
Indeed is necessary to use a endcopy command when we use
a copy instruction.
The code should be this :
$res = $db->exec('COPY temp FROM stdin');
open (FIC,'<result.res');
while (<FIC>) {
$db->putline($_);
}
$db->putline("\\.\n");
$db->endcopy;
close(FIC);
The most important is the $db->putline("\\.\n"); with \n before use endcopy. My error had to omit this :-)
Today my copy code works fine :-)

Indeed my user is http and is not the superuser. In my host superuser postgresql is user postgres.

Ok, thanks for this information, but i find it's a pity because on all my code i use the user http for to access
tables and I do not see why it would be necessary that I connect differently to use command Copy : - ( for
access directly to my file.
Perhaps a problem of security ?
Thanks
