This is a simplification and a way to make it consistent with
how we do Postgres imports (see 6d89319822), using
files coming from the server, not from the local machine.
By encouraging people NOT to use local files,
we potentially avoid problems such as #34 (Github issue),
where people would download `media_store` to their Mac's filesystem
and case-sensitivity issues will actually corrupt it.
By not encouraging local files usage, it's less likely that
people would copy (huge) directories to their local machine like that.

# Importing an existing Postgres database from another installation (optional)
|
|
|
|
Run this if you'd like to import your database from a previous installation of Matrix Synapse.
|
|
(don't forget to import your `media_store` files as well - see [the importing-media-store guide](importing-media-store.md)).
|
|
|
|
|
|
## Prerequisites
|
|
|
|
For this to work, **the database name in Postgres must match** what this playbook uses.
|
|
This playbook uses a Postgres database name of `homeserver` by default (controlled by the `matrix_postgres_db_name` variable).
|
|
If your database name differs, be sure to change `matrix_postgres_db_name` to your desired name and to re-run the playbook before proceeding.
|
|
|
|
The playbook supports importing Postgres dump files in **text** (e.g. `pg_dump > dump.sql`) or **gzipped** formats (e.g. `pg_dump | gzip -c > dump.sql.gz`).
|
|
|
|
Before doing the actual import, **you need to upload your Postgres dump file to the server** (any path is okay).
|
|
|
|
|
|
## Importing
|
|
|
|
To import, run this command (make sure to replace `<server-path-to-postgres-dump.sql>` with a file path on your server):
|
|
|
|
ansible-playbook -i inventory/hosts setup.yml --extra-vars='server_path_postgres_dump=<server-path-to-postgres-dump.sql>' --tags=import-postgres
|
|
|
|
**Note**: `<server-path-to-postgres-dump.sql>` must be a file path to a Postgres dump file on the server (not on your local machine!).
