pgsql.so не подключается

народ! Прошу помощи, никак не получается подключить библиотеку pgsql.so и pdo_pgsql.so

Суть такая... Я начинал работу с сервером через админку webuzo Она установила php в свой каталог

    PHP Version 5.6.38
        Configuration File (php.ini) Path   /usr/local/apps/php56/etc
        Loaded Configuration File   /usr/local/apps/php56/etc/php.ini
        Scan this dir for additional .ini files     /usr/local/apps/php56/etc/php.d
        Additional .ini files parsed    /usr/local/apps/php56/etc/php.d/extra.ini 
        extension_dir   /usr/local/apps/php56/ext/

PostgreSQL - они могут установить только в платной версии, а зачем мне это? :) я и сам могу. Но видимо не могу...

Я установил расширение

yum install php-pgsql

Нашел мои библиотеки по пути

/usr/lib64/php/modules/pgsql.so 
/usr/lib64/php/modules/pdo_pgsql.so

Скопировал в extension_dir /usr/local/apps/php56/ext/ Прописал в /usr/local/apps/php56/etc/php.d/extra.ini

Теперь я вижу расширения

# cat /usr/local/apps/php56/etc/php.d/extra.ini

Но они не подключаются

print_r(get_loaded_extensions());
