Common Lisp library for interacting with PostgreSQL databases
Features efficient communication with the database server without need for foreign libraries, support for UTF-8 on Unicode-aware Lisp implementations, a syntax for mixing SQL and Lisp code, convenient support for prepared statements and stored procedures, a metaclass for simple database-access objects . The biggest differences between this library and CLSQL/CommonSQL are that Postmodern has no intention of being portable across different SQL implementations (it embraces non-standard Postgres features), and approaches extensions like lispy SQL and database access objects in a quite different way. This library was written because the CLSQL approach did not really work for me, your mileage may vary.
