I'm using ghcr.io/zalando/spilo-15:3.2-p1 (tried also with other versions) and when i try to restore db from WAL backup i have following error:

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.
