Quite often, due to a whole spectrum of reasons (data proximity, performance, platform independence) we want to store not only data, but also the application logic in the database. However, the lack of time-proven best practices for development, absence of libraries and frameworks, archaism-like and inexpressive features of SQL and pl/pgsql prevent many modern programmers from doing so. Would it be possible to change the way the things are? Is it possible to create a comfortable and dynamic ecosystem for application programmers that will allow them to solve their tasks effectively, as well as share their code and experiences? Can PostgreSQL permit to manage not only data, but also the code base in an efficient manner?
