You haven't made any argument why this shouldn't be solvable at the
client side, or at worst with a plpgsql DO block; either of which answer
would have the considerable merit of working against existing server
releases.
But in any case I see no reason to mess with the regclass code.
The C code you want is just
names = stringToQualifiedNameList(class_name);
result = RangeVarGetRelid(makeRangeVarFromNameList(names), true);
and there is no way that refactoring is going to yield a solution more
elegant than just duplicating those two lines --- especially since
regclassin has other cases for which zero is a non-error result.
