Requirements
On PHP 5.3, you may encounter this error.
Cannot create new link. Too many open links
I did with Archlinux. pgsql.so was active.
To resolve the issue, I had to active pdo.so and pdo_pgsql.so. Hope this helps!
Installation
In order to enable PostgreSQL support, --with-pgsql[=DIR] is required when you compile PHP. DIR is the PostgreSQL base install directory, defaults to /usr/local/pgsql. If shared object module is available, PostgreSQL module may be loaded using extension directive in php.ini or dl() function.

On a Windows server, configured with Apache, adding the following line to httpd.conf to load libpq.dll can save you a lot of time :
LoadFile "C:/Program Files/PostgreSQL/8.4/bin/libpq.dll"
Note that you will have to change your folder accordingly to the installation path and version of PostgreSQL you have installed. Also note that having Apache and PostgreSQL on the same server for production environments is not recommended.

If you chose NOT TO replace the newer (>5.2.6) php_pgsql.dll with the old one (from 5.2.5) as mentioned in the note above, then libpq.dll must be available in your PATH.
Also note that the libpq.dll that comes with your installation of PostgreSQL will not work. You have to use the one available here:
http://downloads.php.net/pierre/libpq-php-4.4.9-5.2.6.zip.
Place the extracted dll in your php root directory (where php.exe resides)

Windows users should be mindful that since 5.2.6 it seems that the version of php_pgsql.dll supplied is dynamically linked and requires libpq.dll.
The version supplied in 5.2.5 is statically linked and does not have this dependency, if you cannot load the Postgres extension grab php_pgsql.dll from the 5.2.5 distribution
