Which is why I think you should not try to build generic images like this. I looked at the source and it seems like s lot of work had been put into creating a fragile mess.

After having been burned several times by images I prefer writing my docker images from scratch (based on the Debian or Alpine images) for production systems. I only use ready-made images for quickly getting something running locally to evaluate it.

I don't even see any tests in the bitnami repo?

How maps are copyrightable then?

It is a lot of work but it is work that for the most part should not have been done. I took a quick look at the code (since I know PG very well) and I would not recommend anyone to use that mess off Bash code which configures PostgreSQL in an annoying and incorrect way and exposed some arbitrarily select settings in the environment (some very rarely used) while you have to do most in the config file. Better to just write your own Docker image for scratch, or use the official PG image of your needs are simple.

This is what happens if you merge every feature request you get and do not have a clear plan or architecture. After reading the code I am happy they are deleting the images, at least if this one is typical.

As a PostgreSQL expert I can write a much better image which suits my needs in one day, which I have also done several times. It would be harder for a non-expery but I do not think a non-expert should use this image due to some footguns I spotted. This kind of generic image is a bad idea and very hard to build.
