# PostgreSQL Commands
|
|
|
|
## Backup database to file
|
|
To backup the database to a file, you can use the following command:
|
|
|
|
```bash
|
|
docker compose exec postgres pg_dump -U aliasvault aliasvault | gzip > aliasvault.sql.gz
|
|
```
|
|
|
|
## Import database from file
|
|
To drop the existing database and restore the database from a file, you can use the following command:
|
|
|
|
{: .warning }
|
|
Executing this command will drop the existing database and restore the database from the file. Make sure to have a backup of the existing database before running this command.
|
|
|
|
```bash
|
|
docker compose exec postgres psql -U aliasvault postgres -c "DROP DATABASE aliasvault;" && \
|
|
docker compose exec postgres psql -U aliasvault postgres -c "CREATE DATABASE aliasvault;" && \
|
|
gunzip < aliasvault.sql.gz | docker compose exec -iT postgres psql -U aliasvault aliasvault
|
|
```
|
|
|
|
## Change master password
|
|
By default during initial installation the PostgreSQL master password is set to a random string that is
|
|
stored in the `.env` file with the `POSTGRES_PASSWORD` variable.
|
|
|
|
If you wish to change the master password, you can do so by running the following command:
|
|
|
|
1. Open a terminal and navigate to the root of the AliasVault repository.
|
|
2. Run the following command to connect to the PostgreSQL container:
|
|
```bash
|
|
docker compose exec -it postgres psql -U aliasvault -d aliasvault
|
|
```
|
|
3. Once connected to the database, you can change the master password by running the following command:
|
|
```sql
|
|
ALTER USER aliasvault WITH PASSWORD 'new_password';
|
|
```
|
|
4. Press Enter to confirm the changes.
|
|
5. Exit the PostgreSQL shell by running `\q`.
|
|
6. Manually update the `.env` file variable `POSTGRES_PASSWORD` with the new password.
|
|
7. Restart the AliasVault containers by running the following command:
|
|
```bash
|
|
docker compose restart
|
|
```
