Usually, a username / password combination works...

<?php

$db = pg_connect("dbname=db user=db");
$nome = $_POST['nome'];
$senha = $_POST['senha'];

$sql = "SELECT * FROM table WHERE nome ='$nome';";
$resultado = pg_exec($db, $sql);
$linhas = pg_numrows($resultado);
if($linhas==0) { //testa se a consulta retornou algum registro
//echo"<html><body>";
echo"<p align="center">Usuário não encontrado!</p>";
echo"<p align="center"><a href="index.html">Voltar</a></p>";
//echo"</body></html>";
}
else {
if ( $senha!=pg_result($resultado, 0, "senha") ) { //confere senha
//echo"<html><body>";
echo"<p align="center">A sua senha está incorreta!</p>";
echo"<p align="center"><a href="index.html">Voltar</a></p>";
//echo"</body></html>";
}
else {
setcookie("");
header("location: http://www.website.com/autenticacao/pg_inic.php") ;
//readfile("pg_inic.php");

RE: user authenticating system with postgresql
I would use

SELECT * FROM table WHERE name='$name' AND password='$password'

Then check how many rows it returns. If 1, correct, otherwise something wrong.

I really miss the pass check, now it´s on the code . But it returns 1 and the corrects user and pass that are stored on the server,
and still says bad password.
Is this line correct?
if ( $senha!=pg_result($resultado, 0, "senha") )
