Not at the moment, although IIRC the guc.c data structures are designed

Perhaps, but the runtime variable route is much more natural from a
user interface perspective, as there are strong parallels with
existing variables. I'll see what I can do in that arena first.
Thanks for the id

I take it there is not way to do this dynamically, for example to
support a dynamically loaded function? All runtime variables are
hard-coded into the backend?
Maybe you can implement your s

Thanks for your help.

The basic thing is to add an appropriate table entry to guc.c. You
might try searching the sources for all references to one of the
lesser-used GUC variables,
I am writing a backend C function whose behavior should depend on the
setting of a new runtime parameter that can be set with SET. I have
several questions concerning how to implement this, as I can find no
information in the documentation.
