# Import PostgreSQL

> Import your PostgreSQL database schema into ChartDB using a single query

## Download Import Script

Download our PostgreSQL import script:

```bash theme={null}
curl -O https://app.chartdb.io/bash-scripts/psql-import.sh
chmod +x psql-import.sh
```

## Usage

Run the script with your database credentials and ChartDB information:

```bash theme={null}
./psql-import.sh \
  -h your-database-host \
  -p 5432 \
  -U your-database-user \
  -d your-database-name \
  -W your-database-password \
  -a your-chartdb-api-key \
  -t your-diagram-id
```

### Required Parameters

* `-h` Database hostname
* `-p` Database port (default: 5432)
* `-U` Database username
* `-d` Database name
* `-W` Database password
* `-a` ChartDB API key
* `-t` Target diagram ID

The script will connect to your database, extract the schema, and automatically import it into your ChartDB diagram.

## Automated Daily Updates

To automatically update your diagram daily using cron, add the following line to your crontab:

```bash theme={null}
# Run at 2 AM every day
0 2 * * * /path/to/psql-import.sh -h host -p 5432 -U user -W pass -d dbname -a api_key -t diagram_id >> /path/to/psql-import.log 2>&1
```

To edit your crontab:

```bash theme={null}
crontab -e
```

<Note>
  **Note:** Replace `/path/to/psql-import.sh` with the absolute path to the
  script and adjust the credentials accordingly. The log file path
  (`/path/to/psql-import.log`) should be in a directory where your user has
  write permissions.
