Laravel 5.5 - DB::statement error with \copy command (POSTGRES) - database

Question

Im trying to use the \copy command from POSTGRES using laravel 5.5, to insert a large file at the DB, but im getting this error bellow.
I tried this way:
DB::statement( DB::raw("\\copy requisicoes FROM '".$file1."' WITH DELIMITER ','"));
Get this error:
SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near "\" LINE 1: \copy requisicoes FROM '/srv/www/bilhetagem_logs/bilhetagem_... ^ (SQL: \copy requisicoes FROM '/srv/www/bilhetagem_logs/bilhetagem_log1_2018-10-29' WITH DELIMITER ',')
Tried this way too:
DB::statement( DB::raw('\copy requisicoes FROM \''.$file1.'\' WITH DELIMITER \',\''));
Get this error:
SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near "\" LINE 1: \copy requisicoes FROM '/srv/www/bilhetagem_logs/bilhetagem_... ^ (SQL: \copy requisicoes FROM '/srv/www/bilhetagem_logs/bilhetagem_log1_2018-10-29' WITH DELIMITER ',')
If i execute the command that returns on the error above with psql line command, works fine
\copy requisicoes FROM '/srv/www/bilhetagem_logs/bilhetagem_log1_2018-10-29' WITH DELIMITER ','
Could somebody helps me? :)
I have to use \copy insted of copy becouse I dont have superuser privilege at the DB.
https://www.postgresql.org/docs/9.2/static/sql-copy.html
COPY naming a file is only allowed to database superusers, since it allows reading or writing any file that the server has privileges to access.

Answer 1

See this article on PostgreSQL and note this line:
Do not confuse COPY with the psql instruction \copy. \copy invokes
COPY FROM STDIN or COPY TO STDOUT, and then fetches/stores the data in
a file accessible to the psql client. Thus, file accessibility and
access rights depend on the client rather than the server when \copy
is used.
\copy is a psql instruction, so you do not need to write \copy, just COPY.

Answer 2

This is my code to import data from sql to pgsql database
First export CSV file with separator '^'
Then import same file into pgsql using copy command
$users = User::select('*')->get()->toArray();
$pages = "id,warehouse_id,name,email,email_verified_at,password,remember_token,created_at,updated_at\n";
foreach ($users as $where) {
$pages .= "{$where['id']}^{$where['warehouse_id']}^{$where['name']}^{$where['email']}^{$where['email_verified_at']}^{$where['password']}^{$where['remember_token']}^{$where['created_at']}^{$where['updated_at']}\n";
}
$file = Storage::disk('local')->put('user.csv', $pages);
if($file){
$data = "";
try {
$file_path = storage_path('app/user.csv');
$data = DB::connection('pgsql')->statement("copy public.users (id, warehouse_id, name, email, email_verified_at, password, remember_token, created_at, updated_at) FROM '$file_path' DELIMITER '^' CSV HEADER ENCODING 'UTF8' ESCAPE '\"';");
} catch (\Exception $e) {
throw $e;
}
}
