System and Environment Handles to PostgreSQL Specific Resources
Two custom classes provide an interface to resources specific to a PostgreSQL database. Note that using these classes reduces your database's portability.
• RWDBPGSEnvironmentHandle is an environment handle returned by RWDBDatabase that provides methods allowing you to access or set various connect time and configuration parameters.
• RWDBPGSSystemHandle contains the PGconn* used by the RWDBConnection, providing direct access to the PostgreSQL libpq API.
