You may want to take a look at Metastorage. It is a code generation tool
that generates Object-Relational mapping classes. It generates self
contained code that does not need any runtime persistence framework.

The generated code uses Metabase API to provide total database
independence, not only at the database access level, but also at the
database schema installation level. Among many other aspects it
abstracts result row range SELECT (LIMIT clause), auto-incremented key
access, etc.. It supports PostgreSQL among many other databases.

You may find more information about Metastorage and Metabase here:
