I'm looking into PG/PLSql code and following code in plpgsql_call_handler looks strange:


         /* Find or compile the function */
         func = plpgsql_compile(fcinfo, false);

/* Mark the function as busy, so it can't be deleted from under us */
         func->use_count++;


I don't have deep knowledge about this part of code. But what happen if in parallel execution "func" will be deleted between these two lines?

This is not a race condition because the backend is single-threaded.

I see. Each backend has own function cache and use_count is for handle recursion usage. Are my assumption correct?

                thanks Zdenek
