commit    e7226dc3eb39d91fb999d58ef52121dd3c8ee9fc
Author:   Alvaro Herrera <alvherre@alvh.no-ip.org>
Date:     Tue May 09 17:58:51 2017 +0000

    Ignore PQcancel errors properly
    
    Add a (void) cast to all PQcancel() calls that purposefully don't check
    the return value, to keep compilers and static checkers happy.
    
    Per Coverity.
