+# Ansible Role: PHP-PostgreSQL
+
+[![Build Status](https://travis-ci.org/geerlingguy/ansible-role-php-pgsql.svg?branch=master)](https://travis-ci.org/geerlingguy/ansible-role-php-pgsql)
+
+Installs PHP [PostgreSQL](https://www.postgresql.org/) support on Linux.
+
+## Requirements
+
+None.
+
+## Role Variables
+
+Available variables are listed below, along with default values (see `defaults/main.yml`):
+
+    php_enablerepo: ""
+
+(RedHat/CentOS only) If you have enabled any additional repositories (might I suggest geerlingguy.repo-epel or geerlingguy.repo-remi), those repositories can be listed under this variable (e.g. `remi,epel`). This can allow you to install later versions of PHP packages.
+
+    php_pgsql_package: php-pgsql # RedHat
+    php_pgsql_package: php7.0-pgsql # Debian
+
+The PHP PostgreSQL package to install via apt/yum. This should only be overridden if you need to install a unique/special package for PostgreSQL support, as in the case of using software collections on Enterprise Linux.
+
+## Dependencies

+  - geerlingguy.php
