Hey, sorry this fell through the cracks without a response for so long. I think the underlying question is "what does standard image mean"?

In #132 which introduced the minimal and standard images, we actually also proposed a third image type full - but we haven't yet built that one. And it might still need some more thought.

I think a legitimate concern is that we don't want the standard to get bloated, and if we're not careful then i do worry it easily could grow until it eventually includes almost all the extensions already packaged for debian. Another related development is the new Postgres 18 feature which may allow us to package extensions as read-only image volumes mounted to the container.

Another thing I wonder about... standard includes all the OS glibc locales by default, but I think nudging people toward ICU by default would be a better choice.

Anyway - in the meantime it's not hard to create your own images based on the CNPG minimal image and add the extensions you need. I think this is a reasonable approach in the short term, because we really want to make sure the path forward for official CNPG images is carefully thought out.
