Detailed Description

All database access goes through instances of these classes. However, not all implementations of this interface need to provide full transactional integrity.

Several implementations of this interface are shipped with libpqxx, including the plain transaction class, the entirely unprotected nontransaction, and the more cautious robusttransaction.
