unable to connect to PostgreSQL server

I'm getting an error message :

Warning: Unable to connect to PostgreSQL server: PQconnectDB() -- couldn't read
postmaster response: errno=104 Connection reset by peer in /var/www/html/test1.php
on line 24

my PHP script is :

if($myconn = pg_connect("dbname=mydb
   host=localhost
   port=443
   user=faudzy
   "))
{ echo "Connection to PostgreSQL server 'localhost' successful<br>\n"; }


how do I fix it ?


thanks.
