Importing Postgres database using the following command: `{{ matrix_postgres_import_command }}`.
|
|
If this crashes, you can stop Postgres (`systemctl stop matrix-postgres`),
|
|
delete its existing data (`rm -rf {{ matrix_postgres_data_path }}/*`), start it again (`systemctl start matrix-postgres`)
|
|
and manually run the above import command directly on the server.
