Could you explain? PostgreSQL cant be compatible in C level, why
the SQL compatibility? (I mean the LANGUAGE 'C' specifically)
I see already three different C interfaces:
1) 7.0.x
2) 7.1.x
3) > 7.1 where is possible to give a generic funtion/struct where the backend can guess the actual params, also with
some docstrings, etc... Per-function interface needs not to change.
How do you see it possible to solve with current LANGUAGE 'fooC'
approach?
