postgis/postgis publishes amd64 only, so every postgres consumer failed
on arm64. The official postgres image serves both architectures and
already ships the contrib extensions bloom, pg_trgm and unaccent.
PostGIS moves into the postgres_libraries registry and is installed from
PGDG (postgresql-18-postgis-3) only for a consumer that declares it as
an extension, which is mobilizon alone. apt update reads every source
list again, because the PostGIS package depends on GDAL from Debian
main, which a PGDG-only update left without an install candidate.
Postgres 18 keeps its cluster in /var/lib/postgresql/18/docker and its
entrypoint treats a volume at the former /var/lib/postgresql/data as an
old database, so the central and the dedicated data volume both mount at
/var/lib/postgresql. Existing 17 clusters are not migrated: their data
directory trips the entrypoint's old-data check and the container
refuses to start.

"""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 official postgres base image
|
|
(the contrib extensions bloom, pg_trgm and 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>
