We probably just need:

CREATE SCHEMA IF NOT EXISTS public

In post_init.sh to successfully add extensions etc

Also if anyone knows solution how i can restore db without creating my own docker image, please help :)

I just changed create_user_functions.sql, added CREATE SCHEMA IF NOT EXISTS public; and with custom docker image restore now works. Still think that this should be added in official containers.

I also created same issue in zalando/spilo repo, closing this issue.
