How to install extension to existing Postgres?

[Daniil Okhlopkov]

Hi!

I need to install Pgrouting extension to my dokku-postgres database which is already populated with a huge amount of data from my Django app. Moreover, this extension requires postGIS to be installed too.

I searched all issues and couldn't find the way how to install it. Maybe someone can help?

I'm on the latest Dokku and latest dokku-postgres now.

Make a custom Dockerfile that installs the extension, build the image, and use it for your database? You'll need to stop/start, but it should work?

I would export the database contents and try it on a new service to verify of course.

Thanks for the reply! I'll try it out and then reopen if I'll have any troubles.
