I just noticed by chance that view relations are using StdRdOptions to allocate their reloptions. I can't find any reason for this, other than someone failed to realize that they should instead have a struct defined of its own, just like (say) GIN indexes do. Views using StdRdOptions is quite pointless, given that it's used for stuff like fillfactor and autovacuum, neither of which apply to views.
9.2 added security_barrier to StdRdOptions, and 9.4 is now adding check_option_offset, which is a string reloption with some funny rules.
Is it too late to redefine the check_option_offset stuff before 9.4 ships, so that it is in its own struct? (I'd hope we can redefine it in a simpler way also, hopefully one that doesn't require strcmp()'ing that string with "local" or "cascaded" every time someone is interested in knowing the option's value for a particular view.)
