Not at the moment, although IIRC the guc.c data structures are designed
to make it possible to add things on-the-fly. (There's a pointer table
that's built dynamically, and in theory could contain more entries than
are in the hardcoded tables.) You'd need to add a routine to actually
add an entry ... and figure out where to call it from ...
