LargeObjectManager

class LargeObjectManager(session: OctaviusSession)

Manager for PostgreSQL Large Objects associated with a specific connection. NOTE: All operations on Large Objects must be performed within a transaction (BEGIN ... COMMIT/ROLLBACK) to be valid in PostgreSQL. Note: PostgreSQL OIDs are unsigned 32-bit integers. In the JVM, they are represented as signed Int, meaning values above 2.14B will appear as negative numbers if printed. This is expected and perfectly safe for database operations.
