Can anyone provide me with some direction on how to write a function
I can load into postgres that will execute a function specified by
OID (or regproc/regprocedure) at runtime, with type safety? I've been
able to write such a function in C, but I was unable to figure out
how to determine the parameters that the specified function expects,
so I can prevent calling a function that doesn't match the expected
signature (which segfaults postgres).
