It is clear from the manual that c-functions can cause the dynamic loading of .so's and that subsequent usage in the same database session will use the already loaded function. But, when the session is done, will the loaded function remain in the server for subsequent sessions? When/how does a dynamically loaded .so get unloaded? I want to avoid preloading .so's at server startup, but also avoid dynamically loading them for ~every~ session.
