Ok,
1. PHPs postgres lib doesn't have a pg_error() function. You want
pg_last_error().
2. Are you using the sid as li_session's primary key? If so, before
you create a new session with an already existing sid, you will need to
delete the old sid entry before inserting a new one with the same sid.

The problem is in the write function of my library. Here it is:
function pg_session_write($sid, $val) {
$life = get_cfg_var("session.gc_maxlifetime");
$exp = time() + $life;
$selQ = "SELECT sidid FROM li_session
WHERE sidid = '$sid' AND exptime >". time();
$selR= pg_query($selQ)or die("It didn't work:". pg_error());
if(pg_num_rows($selR)) {
$sesupQ ="UPDATE li_session SET
exptime = '$exp', vidval = '$val'
WHERE
sidid = '$sid' and exptime >". time();
$sesupR=pg_query($sesupQ) or die("It didn't work:". pg_error());
} else {
$sesinQ = "INSERT INTO li_session
VALUES('$sid', '$val', '$exp')";
$sesinR= pg_query($sesinQ) or die("It didn't work:". pg_error());
}
}
