HAWQ-978. Fixed deadlock in signal handler which call asynchronous unâ¦
â¦safe functions elog()
(1) Can not call elog() in signal handler function, because elog() will
cascade call some unsafe function.
(2) When CheckStatementTimeout() called, "canceling statement due to
statement timeout" will be printed out, so we don't need to re-print it.
