My Bad Nathan, was looking at PG 11, 14 codes. Just to be sure, calling ProcessConfigFile is a bug from a signal handler is a bug, right? Since it uses AllocSetContextCreate & also GUC variables changes might not be visible in regular flow.
I saw the discussion of the commit but couldn't conclude from the discussion that it was changed due to ProcessConfigFIle.
