I'm looking into PG/PLSql code and following code in

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
