Starting with PHP 7, on Ubuntu (i.e., 16+), you can run:
`sudo apt-get install php-pgsql`
为启用 PostgreSQL 支持，编译 PHP 时需要 --with-pgsql[=DIR]。DIR
是 PostgreSQL 的基本安装目录，默认是 /usr/local/pgsql。如果共享对象模块可用，可以使用 php.ini
中的 extension 指令或者 dl() 函数加载 PostgreSQL 模块。
Starting with PHP 7, on Ubuntu (i.e., 16+), you can run:
`sudo apt-get install php-pgsql`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.
