# PostgreSQL

## Description
4+
5+
**NOTE**: The Postgres plugin is a contrib plugin. This means it may not be fully stable.
6+
7+
8+
The PostgreSQL data source allows for the retrieval of historical feature values from a PostgreSQL database for building training datasets as well as materializing features into an online store.
9+
10+
## Examples
11+
12+
Defining a Postgres source
13+
14+
```python
15+
from feast.infra.offline_stores.contrib.postgres_offline_store.postgres_source import (
16+
PostgreSQLSource,
17+
)
18+
19+
driver_stats_source = PostgreSQLSource(
20+
name="feast_driver_hourly_stats",
21+
query="SELECT * FROM feast_driver_hourly_stats",
22+
timestamp_field="event_timestamp",
23+
created_timestamp_column="created",
24+
)
25+
```

# PostgreSQL (contrib)

3+
## Description
4+
5+
The PostgreSQL offline store is an offline store that provides support for reading [PostgreSQL](../data-sources/postgres.md) data sources.
6+
7+
8+
**DISCLAIMER**: This PostgreSQL offline store still does not achieve full test coverage.
9+
10+
* Entity dataframes can be provided as a SQL query or can be provided as a Pandas dataframe. Pandas dataframes will be converted to a Spark dataframe and processed as a temporary view.
11+
* A `SparkRetrievalJob` is returned when calling `get_historical_features()`.
12+
* This allows you to call
13+
* `to_df` to retrieve the pandas dataframe.
14+
* `to_arrow` to retrieve the dataframe as a PyArrow table.
15+
16+
## Example
17+
18+
{% code title="feature_store.yaml" %}
19+
```yaml
20+
project: my_project
21+
registry: data/registry.db
