The base image postgis/postgis:17-3.5 is Debian 11, whose archive was decommissioned on 2026-08-31. The pgvector layer pulled 174 MB of build toolchain from deb.debian.org, and those pool files are now purged while the index still advertises them: linux-libc-dev 404'd on 44 of 44 attempts across four Fastly POPs. Since 2026-09-07 the suite's InRelease is also expired, so apt-get update itself exits 100. PGDG ships postgresql-17-pgvector prebuilt and its bullseye-pgdg suite is alive, so reading only the pgdg.list the image writes itself removes deb.debian.org from the build entirely. Verified on the exact mirrored base image: the package installs, vector.so lands, zero bytes fetched from deb.debian.org. Signature verification is untouched - no Acquire::Check-Valid-Until. Side effect worth naming: the old recipe cloned pgvector.git with no tag or ref, so every rebuild baked unpinned master into the central RDBMS. It is now pinned at 0.8.6-1.pgdg11+1. The base image is still EOL and its migration remains open. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

"""Resolve postgres-extension library install recipes.
|
|
|
|
Usage:
|
|
{{ lookup('postgres_libraries', ['vector', 'bloom']) }}
|
|
|
|
Takes a list of extension names and returns the subset that needs a
|
|
custom library install on top of the postgis/postgis base image
|
|
(bloom, postgis, pg_trgm, unaccent are already in the base — those are
|
|
filtered out). Each returned entry is a dict with:
|
|
- extension: the extension name (matches the SQL identifier)
|
|
- name: the library/source name (used in the Dockerfile context)
|
|
- apt_package: the PGDG package suffix, installed as
|
|
postgresql-<major>-<apt_package>
