Personally, I'd recommend using *one* -I switch and having .c files reference extension headers with #include "extensionname/headername.h". As I said before, I think that we should change the existing contrib modules to be coded likewise, all using a single -I switch that points at SRCDIR/contrib. That'd help give people the right coding model to follow. regards, tom lane
