 Well, yes.  :)
 I would even drop the GUC setting, but hypothetically there could
 be some sort of backwards compatiblity concerns, so I added it
 to patch and kept old default.  But if noone has strong need for it,
 the setting can be removed.
I think the default behaviour should be the one we recommend (which would be to have the server one be preferred). But I do agree with the requirement to have a GUC to be able to  remove it - even though I don't like the idea of more GUCs. But making it a compile time option would make it the same as not having one...
