Alpine is a much smaller version of Linux, it results in a smaller container than the full postgres image. It is argued that because of its small size, alpine is also more secured. Although one disadvantage of alpine is that it contains a lot less functionality than a docker image running the full Linux OS.

If you click on those tags, you'll see the underlying Dockerfile. One is based on debian, the other on alpine.
