Implements data-aware operations for working with a PostgreSQL database.
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 Firebird 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:
