Hi,
I just wanted to announce a new binding to libpq for PHP I've been working on, pecl/pq; licensed under a 2-clause-BSD license and supporting PostgreSQL 9.0 and up.
It's hosted on PECL:
http://pecl.php.net/package/pqDocumentation is published at:
http://devel-m6w6.rhcloud.com/mdref/pq
On any other Linux flavor, you should be able to install it with the pecl command (probably in an php-devel package):
# pecl install pq-beta
Happy coding!
