Hello!
My colleague Victoria Shepard reported that pgbench might crash
during initialization with some values of shared_buffers and
max_worker_processes in conf.
After some research, found this happens when the LimitAdditionalPins() returns exactly zero.
In the current master, this will happen e.g. if shared_buffers = 10MB and max_worker_processes = 40.
Then the command "pgbench --initialize postgres" will lead to crash.
See the backtrace attached.
There is a fix in the patch applied. Please take a look on it.
With the best regards,
