Answer 1

It looks like you are missing module called pdo_pgsql.
Look in your php.ini for a line extension=php_pdo_pgsql.dll. It should be uncommented.
On Ubuntu or other linux distribution you can install PDO driver with something like
apt-get install php5-pgsql.

Answer 2

I was also facing this problem into xampp now its works for me, May be it will helpful to you also in linux platform lamp or latest version of Php 5.6 - 7.
Just uncomment these lines from php.ini file
extension=pdo_pgsql
extension=pgsql
Example from my php.ini file

Answer 3

The earliest answers forgot to mention that you need to restart some services after enabling the following in php.ini file:
extension=pdo_pgsql
extension=pgsql
You need to restart your web server, in my case my using nginx, so I do
sudo systemctl restart nginx.service
After that I restart php-fpm using:
sudo systemctl restart php-fpm.service
Thats All...cheers
