I did some research and ended up getting the following result.
You have not enabled the Postgresql module on your server.
If you have it, enable php.ini by removing the ';'
Windows:
- Edit php.ini: Extension=php_pgsql.dll
Linux:
- Install the module: php-pgsql
- Edit php.ini: Extension=pgsql.so
Tutorial:
Linux: Configure Postgresql to Work With PHP
Windows: PHP COM POSTGRESQL
Since you have already said that you modified php.ini and are using Uolhost that and according to their support:
Our PHP supports the Mysql and SQL Server databases. Also installed are modules for access to Postgresql and Firebird (which can be accessed remotely).
NOTE: It is always recommended to access the databases in the same local network. If there are performance issues accessing a remote base, we may contact and disable the hosting service.
This way I advise you to look directly to the support of Uolhost to check its settings and if it is the case to make some release of some specific module
On which host are you putting your [tag:wordpress]?

I’m using the Uolhost

I actually just did a search and it can only be something related to the extensions of [tag:postgresql] in [tag:php]
