Use the source, Luke.
The tables in src/backend/utils/misc/guc.c are the authoritative reference.
Read the comments in src/include/utils/guc.h first.
Yes, everything in postgresql.conf is a GUC variable; but I think there
may be some GUC variables that were omitted from postgresql.conf.
Hopefully intentionally, not by oversight ...
