Lisp

As the title says, I am looking for a library that can connect to Progres and execute a stored procedure with either input or output parameters. Or even a user defined function.

I've checked the documentation of these three libraries:

• cl-progres
• pg-dot-lisp
• clsql

but there seems to be no mention or example of executing a stored procedure. Is it just not documented? Are there other ways I can do it apart from these three?
