Large object support in POSTGRES
Michael R Stonebraker, M. Olson · 2002
Four implementations that support large objects in the POSTGRES database system are presented. The four implementations offer varying levels of support for security, transactions, compression, and time travel. All are implemented using the POSTGRES abstract data type paradigm, support user-defined operators and functions, and allow file-oriented access to large objects in the database. The support for user-defined storage managers available in POSTGRES is also detailed. The performance of all four large object implementations on two different storage devices is described.>
