Thank you  wavemind for your concern! I just start from scratch because I couldn't figure it out. I also change the name for my devcontainer/compose.yml and devcontainler.json file and used different one from my app and just worked. I don't know if that was the problem but on a second thought after your comment that you had to stop the local postgres server I give more chances to be that.
