Maybe I missing something here. Even adding those two lines to the extensions
in core and contrib is going to end up being more lines than what I proposed?
What portability issues do you forsee? We already look up the same symbol in
all the shared libraries ("Pg_magic_func"), so we know that we can deal with
duplicate function names. Are you thinking that somehow we'd end up with
symbol interposition or something?
