# We used to store Postgres data directly under `/matrix/postgres` (what is now considered `matrix_postgres_base_path`).
|
|
#
|
|
# From now on, we expect to store Postgres data one directory below now (`/matrix/postgres/data` - `matrix_postgres_data_path`).
|
|
# We wish to use the base directory for other purposes (storing environment variable files, etc.).
|
|
# Mixing those with the Postgres data is no good and it leads to Postgres's `initdb` complaining to initialize
|
|
# a database in a non-empty directory.
|
|
#
|
|
# For this reason, we store the Postgres data in `/matrix/postgres/data` and need to relocate any installations
|
|
# which still store it in the parent directory (`/matrix/postgres`).
|
|
#
|
|
# This utility is intentionally not in `tasks/util`, because if it were, it wouldn't be possible
|
|
# to include it in other roles via the import_role module: https://docs.ansible.com/ansible/latest/collections/ansible/builtin/import_role_module.html

Found that you have Postgres data in `{{ matrix_postgres_base_path }}`.

We'll stop Postgres and relocate the files there for you.
