--> $db=pg_connect("$db_con_str");
On this line remove the ; at the end. You are completing a command end then continuing it on the next line with the 'or' statement.

It should look like this
$db=pg_connect("$db_con_str")
or die("cannot connect to db.");

Or another way of completing the same task is
$db=pc_connect("$db_con_str");
if(!$db) {
//You can log the failure in a log file
//or anything you want.
//Print out a full html error page
//then use the die statement
die()
}

also, your headers seems a bit weird to me:

header ("location: name taken.php? login_id=$login_id");

if the page you want to redirect to has a space in its name, you better replace it by an underscore.. its more reliable and not supported on unix servers I think, i would make this of it:

header ("location: name_taken.php?login_id=$login_id");
