Hi,

Is it possible to have static variable inside pgSQL C functions (or)
PL/pgSQL?? I'm having a use case where I need to update a counter inside the
function & it should be thread-safe.

I've tried using static variable inside the C function along with
pthread_mutex_lock/pthread_mutex_unlock. And found functions are not shared
among each other. 

Thanks,
Athi
