Thanks a lot Heikki and Albe. Exactly what I was asking for. Heikki: the libraries are written in languages that have their own runtime and their documentation insists that both init and dispose calls are performed when used from C. PG_init() and proc_exit sounds spot on.
You might also consider creating your own PL handler for those languages. Or google around if one exists already.
Any ideas about keeping some data at session level between calls? Both calls of the same function and different C functions. (though temp table is always there as an option)
You can use a global variable in the C extension. If you need to allocate memory that survives across function calls, use "MemoryContextSwitchTo(TopMemoryContext); ... = palloc(...)". I'm sure you'll find examples of that in the existing extensions too.
