Error Message

Answer 1

To hide the error text generated by PHP, add @ in front of the function call, e.g.:

$conn = @pg_connect("host=$HOST dbname=$DBNAME user=$USER ".
                   "password=$PASSWORD sslmode=disable");

Answer 2

pg_connect does not throw exception, so you have to translate to exception like below.

function exception_error_handler($errno, $errstr, $errfile, $errline ) {
    throw new ErrorException($errstr, $errno, 0, $errfile, $errline);
}
set_error_handler("exception_error_handler");

try {
    $conn=@pg_connect("host=dbhost user=dbuser dbname=db password=dbpass");
} Catch (Exception $e) {
    Echo $e->getMessage();
}
