As I understood variables are stored in pg_class table. Did you consider
storing variables in a special catalog table? It can be named as
pg_variable.

pg_variable table requires more code of course, but it would fix the issues:
- pg_class has a lot attributes which are not related with variables,
  and I think variables don't need many of them
- in a future variables might want to have some additional attributes
  which are not needed for relations, you can easily add them to
  pg_variable

What do you think?
