Subject: Fix kill() call in elog() so that it gets its own pid by calling getpid().
X-Git-Tag: REL6_5~378
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=075dc252c7b887f1f5871b2c96d8f6ddf869bda2;p=thirdparty%2Fpostgresql.git

Fix kill() call in elog() so that it gets its own pid by calling getpid().
MyProcPid global variable is set to 0 when postgres starts as a command
(not as a backend daemon). This leads issuing SIGQUIT to the process group,
not the process itself. As a result, parent sh gets core dumped in the
Wisconsin benchmark test.
