Docker PHP with pdo_pgsql install issue
Oh dang I figured it all out. So everything I have above does work. Something weird was happening with how Docker was caching. I wasn't updating the image correctly I guess. I simply removed all containers and images and then rebuilt and ran it all and it just magically worked. Also had a couple of permissions issues on certain directories and files along the way.
Hope the above snips help someone, there is not a lot of docs on dockers php-apache image with pdo_pgsql.
