Hello,

I've made no update to my repo for a few months, however I am getting an error with the codespace start up

I see a merge on go/ go-postgres but don't think this is related #362

I was getting this, too. I fixed it by changing the postgres image from postgres:latest to postgres:17-trixie and that seems to have fixed it for me. I chose trixie just to be consistent because I'm also running a ruby trixie image(see below), not sure if that matters or just locking the version from latest which might have an issue to 17 which doesn't....
