PostgreSQL DataSource

PostgreSQL provides three JDBC DataSource implementations, namely; PGConnectionPoolDataSource, PGPoolingDataSource, and PGSimpleDataSource. Their pooling data source implementations are deprecated, and you should use a more modern connection pooling implementation, such as those described in the Examples section.

To wire those up:

• use org.postgresql.Driver as the driverClassName.

• use a JDBC URL based on the following format: jdbc:postgresql://[hostname]:[port]/[database][?properties]
