Description:

When I make a call to pg_pconnect(), I get the error:

Warning: pg_pconnect(): Cannot create new link. Too many open links (0). 

My system configuration:

PHPInfo() for pgsql:

pgsql
PostgreSQL Support enabled 
PostgreSQL(libpq) Version  7.4.2  
Multibyte character support  enabled  
SSL support  enabled  
Active Persistent Links  0  
Active Links  0  

Directive Local Value Master Value 
pgsql.allow_persistent On On 
pgsql.auto_reset_persistent Off Off 
pgsql.ignore_notice Off Off 
pgsql.log_notice Off Off 
pgsql.max_links 150 150 
pgsql.max_persistent 100 100 


Note that .max_links and .max_persistent were originally set to unlimited in php.ini (ie -1) but I tried changing the values to determine if the outcome would be different.

I realise that bug reports for previous versions (6+ months ago) have been submitted and answered, but I've read them and they do not solve the issue, they just suggest using the latest stable version of php4 

Reproduce code:
---------------
function connect()
{

        $this->dsn = "host='" . $this->hostName . "' port='" . $this->port . "' dbname='" . $this->database . "' user='" . $this->userName . "' password='". $this->passwd . "'";

        $this->link = pg_pconnect($this->dsn);
...
        return $this->link;
}

This code was tested and working using previous version of php4 / php4-pgsql packages as described above.

The line that causes the error is 
$this->link = pg_pconnect(...);



Expected result:
----------------
expect connection to be made to the postgres database.


Actual result:
--------------
Actual result is a warning, not a crash.
