 You're right - on my machine the default compiler is llvm too:

 However, postgresql91 segfaults for me without postgresql91-llvm-
 gcc-4.2.diff and works fine with postgresql91-llvm-gcc-4.2.diff applied.
 Perhaps MacPorts defaults to clang even though the system default compiler
 is llvm-gcc? https://trac.macports.org/wiki/ProblemHotlist suggests that:
 ''If a port foo fails to build and you're using Xcode 4.2 or later, the
 default compiler is clang; try compiling with llvm-gcc-4.2 instead''

 Have you tried doing a "\dt" on a postgresql91 built on 10.7 with Xcode
 4.2? Did it work for you with/without the patch?
