I see you have posted the same question on:
http://uk.php.net/manual/en/function.pg-connect.php:
On that page, it says:
==================================================================
Return Values
PostgreSQL connection resource on success, FALSE on failure.
==================================================================
I admit that it does not give an example about error handling.
On http://uk.php.net/manual/en/function.pg-last-error.php, it says
========================================================================
Parameters
connection
PostgreSQL database connection resource. When connection is not
present, the default connection is used. The default connection is the
last connection made by pg_connect() or pg_pconnect().
========================================================================
which suggests that you can say
if ($pgsql_conn) {
print "Connexion réussie à : " . pg_host($pgsql_conn) . "<br/>\n";
} else {
echo pg_last_notice();
exit;
}
but I have not tried it. The example on that page does what you have
done, which suggests that you have found a bug either in the code or in
the documentation.
Sorry I can't be more helpful
