+# PostgreSQL
+
+## Description
+
+**NOTE**: The Postgres plugin is a contrib plugin. This means it may not be fully stable.
+
+
+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.
+
+## Examples
+
+Defining a Postgres source
+
+```python
+from feast.infra.offline_stores.contrib.postgres_offline_store.postgres_source import (
+    PostgreSQLSource,
+)
+
+driver_stats_source = PostgreSQLSource(
+    name="feast_driver_hourly_stats",
+    query="SELECT * FROM feast_driver_hourly_stats",
+    timestamp_field="event_timestamp",
+    created_timestamp_column="created",
+)
+```

+# PostgreSQL (contrib)
+
+## Description
+
+The PostgreSQL offline store is an offline store that provides support for reading [PostgreSQL](../data-sources/postgres.md) data sources.
+
+
+**DISCLAIMER**: This PostgreSQL offline store still does not achieve full test coverage.
+
+* 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.
+* A `SparkRetrievalJob` is returned when calling `get_historical_features()`.
+  * This allows you to call
+     * `to_df` to retrieve the pandas dataframe.
+     * `to_arrow` to retrieve the dataframe as a PyArrow table.
+
+## Example
+
+{% code title="feature_store.yaml" %}
+```yaml
+project: my_project
+registry: data/registry.db
+provider: local
+offline_store:
+  type: postgres
+  host: DB_HOST
+  port: DB_PORT
+  database: DB_NAME
+  db_schema: DB_SCHEMA
+  user: DB_USERNAME

+The PostgreSQL online store provides support for materializing feature values into a PostgreSQL database for serving online features.
+
+* Only the latest feature values are persisted

+```yaml
+project: my_feature_repo
