Getting back to propogating SIGHUP to the children, if I have issued a
SET in my session, does a postmaster SIGHUP wipe that out, and even if
it doesn't, what if I do a SHOW early in my session, see the setting is
OK, then find later that is is changed, for example, the ONLY
inheritance setting.  I guess what I am saying is that I see session
stability as a feature, rather than propogating changes to running
children, which I think could cause more harm than good.
