Undefined column: 7 ERROR: column "email" does not exist - Laravel 5.4 validation "unique" with PostgreSQL?

Question

PostgreSQL

Validation field:

'email' => 'required|filled|string|email|max:125|unique:pgsql.public.users, email',

Class:

class User extends Authenticatable
{
    use Notifiable, SoftDeletes;

    protected $table = "pqsql.public.users";

Mistake:

QueryException in Connection.php line 647:
SQLSTATE[42703]: Undefined column: 7 ERROR: column " email" does not exist
LINE 1: ...count(*) as aggregate from "public"."users" where " email" =...
^
HINT: Perhaps you meant to reference the column "users.email". (SQL: select count(*) as aggregate from "public"."users" where " email" = [email protected])

If you do validation only on the users table, everything works, as soon as I put it on the field, it gives this error.
Why does he not see the field, but sees the table?

Answer 1

Remove the space between the table name and the field.
"email"
/\ This one.

'email' => 'required|filled|string|email|max:125|unique:pgsql.public.users,email',
