Remarks

The PostgreSqlConnectionProvider class implements data-aware operations for working with PostgreSQL databases. In most cases, there is no need to create connection providers explicitly, as they are created automatically by a Session object based upon a connection string.

To connect to a specific PostgreSQL database, you can generate a connection string via the static PostgreSqlConnectionProvider.GetConnectionString method. This connection string will contain information on the provider ( PostgreSqlConnectionProvider ) that will be used to work with the database. Supply this connection string to a Session object (for instance, via the Session.ConnectionString or XpoDefault.ConnectionString property). When a connection to a database is to be established, the session will create a corresponding connection provider based upon the connection string and then perform all data-aware operations using this connection provider.

There are also cases when you need to create a connection provider explicitly via its constructor, for instance:

When sharing a single IDataLayer object between multiple sessions, a connection provider should be passed to the data layer’s constructor. See the IDataLayer topic for additional information.
When manually maintaining a connection pool.
