This chapter describes the RScheme interface to the PostgresQL Data Base Management System (formerly known as Postgres95). The interface (glue) functionality is contained in an RScheme package, pg95, which provides a single module by the same name[1].
In order to make use of a PostresQL database, you must establish a connection to it. You may connect to databases on other hosts or on ports other than the default by specifying appropriate keywords to the postgres-connect function.
