Description:
------------
I upgraded to php 4.3.3, and started receiving this error when connecting to postgres:

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

I use the same configure line with php 4.3.2:

./configure --with-apxs=/usr/local/apache/bin/apxs --with-curl --with-xml --with-mysql=/usr --with-ssl --with-mcrypt
--enable-xslt-sablot --with-gd --with-jpeg-dir=/usr/bin/cjpeg --with-zlib --with-ttf --with-pgsql 

php.ini file remains the same:
; Maximum number of links (persistent+non persistent).  -1 means no limit.
pgsql.max_links = -1

When I re-install 4.3.2, the problem goes away.

Reproduce code:
---------------
$bd_db = pg_connect ("host=$hostname dbname=$database_name user=$username password=$password");

Expected result:
----------------
A connection to the database given

Actual result:
--------------
PHP Warning: pg_connect(): Cannot create new link. Too many open links (0).

This version had the exact same problem.

How many apache children do you have at maximum and how many connections (at maximum) does your postgreSQL allow to connect?

I just had this same problem.  The problem stemmed from have 
two sets of "extension=" lines, first in /usr/local/etc/
php.ini, also in /usr/local/etc/php/extensions.ini.  Removing 
them from the php.ini file solved the problem.

I'm using ubuntu 7.10 and I get this problem fixed when I take out the file 
pdo_pgsql.ini from /etc/php5/apache2/conf.d/ and put its content into 
/etc/php5/apache2/conf.d/pgsql.ini.

Only restart apache2 and that's all.
