Testing Postgresql in Java: Embeded PG vs PG in docker?

Question

PostgreSQL

Has anyone compared Embeded PostgreSQL with PostgreSQL in docker in java testing?
What are the differences in convenience, speed Embeded PostgreSQL versus PostgreSQL in Docker?
There is a mini project https://gitlab.com/anton_patsev/gs-actuator-service
I wanted to add PostgreSQL testing to docker in Spring Boot Actuator.
For example, https://vertex-academy.com/tutorials/en/kak-podkly...
If you run Java tests for PostgreSQL in docker, will the java tests be faster than the Java tests for Embeded PostgreSQL?
