I have begun to use some static variables in my c-language
functions to maintain state (3rd party licensing issues) during
the course of a session (postgres process, spawned by postmaster).
These are declared static outside the scope of any function.
(is global the correct term anymore?)
When I use dynamic loading of my .so,
each session is independent, with its own static variables.
Will the same be true if I were to load the .so once when
the database starts up? Or will there be just one set of
static variables for all sessions?
