When I use checkpoint command, the coordinator report the error as belows.Is it a bug or something?
template1=# checkpoint;
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: LOG: server process (PID 20650) was terminated by signal 11: Segmentation fault
LOG: terminating any other active server processes
