Hello

Server crash on code

dump begin for i in 1..10 loop raise notice '%', i; end loop; return;
end $$ language plpgsql;
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: Failed.
