@yosifkit Is there a way to point to this and provide an image name so I can run a Postgres 19.1 RC1 with Docker locally? Thanks.

[yosifkit]

Yeah, that'll be something like one of the below and you'll have a postgres:19beta1-trixie locally.

$ docker buildx build -t postgres:19beta1-trixie 'https://github.com/infosiftr/postgres.git#19-rc:19/trixie'
$ # alternatively using the PR as the reference
$ docker buildx build -t postgres:19beta1-trixie 'https://github.com/docker-library/postgres.git#refs/pull/1415/merge:19/trixie'

Thank you @yosifkit, up and running:

I ran:

docker buildx build -t postgres:19beta1-trixie 'https://github.com/infosiftr/postgres.git#19-rc:19/trixie'

Then I ran:

docker run \
  --name pg19 \
  --env POSTGRES_USER=postgres \
  --env POSTGRES_PASSWORD=postgres \
  --detach postgres:19beta1-trixie

And connected to psql via:

docker container exec -it pg19 psql -U postgres

psql (19beta1 (Debian 19~beta1-1.pgdg13+1))
Type "help" for help.
