GUC parameters that silently alter the semantics of SQL statements
should be introduced only with great trepidation, not just because
someone thought them up one day.  What is the real use-case for
this bit of complication?  Given the very short list of supported
reloptions right now, why would you imagine that there will ever
be such a thing as installation-local reloptions?
