This MR updates our "LongRunningQueries" runbook to suggest using
pg_terminate_backendoverpg_cancel_backend. The reason is that cancelling a query though being the most graceful way will not always work which can be confusing for people following the runbook in duty.Using
pg_terminate_backendis more consistent and still is a safe approach to killing PG processes as it merely sends aSIGTERMsignal to the backend process.
