Hi :
 Im trying to run this CGI.

#!/usr/bin/perl -w

use Pg;


print "Content-type: text/html\n\n";

$database = "henric";
$server = "iris1.ingenieria.uatx.mx";
$conn = Pg::setdb($server,5432,'','',$database);
$namedb = $conn->db;
$error = $conn->errorMessage;

print <<EOF;
<html>
<head><title>Resultados de Postgres</title></head>
<body>
<h1>Hola mundo</h1>Conectado a la base de datos: $namedb<br>
EOF

if ($error ne '') {  print "ERROR: ", $error;  print "</body></html>\n";  exit 1; }

print"Hasta aqui todo esta bien!!";
print qq (
</body>
</html>);

When type perl conexion.cgi <enter> i get the next result.

iris1% perl conexion.cgi
Content-type: text/html

<html>
<head><title>Resultados de Postgres</title></head>
<body>Conectado a la base de datos: henric<br>
Hasta aqui todo esta bien!!
</body>
</html>iris1% 
I think that all it's O.K and then i try to run it in a browser and i
get the next result.

Conectado a la base de datos: henric
ERROR: FATAL 1: SetUserId: user 'nobody' is not in 'pg_shadow' 

 What's wrong?

Im using Pg in the new Style.

       Looks like you need to run the PostgreSQL "createuser"
utility to create an entry for "nobody". Then you'll have to
give "nobody" read access to the data the web page is accessing.

I recommend using the CGI module for perl CGI.  It'll make your life a 
lot easier (you don't need to use the here documents).

Your web server typically intiates connections under user 'nobody', for
security reasons (nobody usually has no default shell, so crackers can't
use it to break into your system).  You need to create a user in Postgres
also called 'nobody' so it cann access your database.  You will then need
to grant whatever rights you need for 'nobody' to use your database (at
least give SELECT rights).   I'm guessing you are using Apache and some 
flavour of Unix, be it Linux, FreeBSD, etc.
