[Build issue]: postgresql-{16,17,18}-oci-entrypoint packages broken

### Package name postgresql-16-oci-entrypoint-base, postgresql-17-oci-entrypoint-base, postgresql-18-oci-entrypoint-base ### Current version in Wolfi _No response_ ### Requested version _No response_ ### Upstream project URL https://github.com/postgres/postgres ### Problem The builds for all postgresql oci-entrypoint-base packages are currently broken. The entrypoint files downloaded from the Docker, Inc. upstream repository during build time only contain the text "404: Not found." ### Steps to reproduce - Create a new docker image based on `cgr.dev/chainguard/wolfi-base:latest` - Install (for example) `postgresql-oci-entrypoint~=17` - Observe that `/usr/libexec/postgresql17/docker-entrypoint.sh` and `/usr/libexec/postgresql17/docker-ensure-initdb.sh` only contain the text "404: Not found." Minimal Dockerfile to reproduce follows: ```Dockerfile FROM cgr.dev/chainguard/wolfi-base:latest AS my-org/postgresql-17 RUN apk add --no-cache shadow gosu glibc-locale-en glibc-locale-de \ "postgresql~=17" \ "postgresql-contrib~=17" \ "postgresql-client~=17" \ "postgresql-oci-entrypoint~=17" \ && useradd -rm postgres \ && apk del --no-cache shadow WORKDIR "/home/postgres" ENV PGDATA="/var/lib/postgresql/data" ENV POSTGRES_INITDB_ARGS="-E UTF8" ENTRYPOINT ["/usr/bin/docker-entrypoint.sh", "postgres"] ``` ### Root cause (if known) - Docker, Inc. has ceased providing Docker images based on alpine 3.21, so requests for these files result in 404 errors. - The build silently continues if there is an issue downloading the files that the OCI entrypoint package is built upon. ### Proposed solution - Increasing `ALPINE_VERSION` in the build files to 3.23 (or at least 3.22) alleviates the immediate issue. - Adding `--fail-with-body` or at least `--fail` to the curl calls for the entrypoint files will ensure the build fails if there is an issue downloading these files in the future. ### Testing performed Manual attempts to download the files used in the build script, but with `3.23` and `3.22` substituted for `${ALPINE_VERSION}`, succeed. ### Acceptance criteria - [x] The requested version is the **latest stable upstream release** (no pre-releases or RCs) - [x] The upstream project uses an **OSI-approved license** - [x] The change aligns with Wolfi’s packaging and security model - [x] The package can be reasonably maintained over time - [x] There are no known unresolved security or supply-chain concerns
