Great!
A couple high-level questions:
1. I notice a lot of use of the LLVM builder, for example, in
slot_compile_deform(). Why can't you do the same thing you did with
function code, where you create the ".bc" at build time from plain C
code, and then load it at runtime?
2. I'm glad you considered extensions. How far can we go with this in
the future? Can we have bitcode-only extensions that don't need a .so
file? Can we store the bitcode in pg_proc, simplifying deployment and
allowing extensions to travel over replication? I am not asking for
this now, of course, but I'd like to get the idea out there so we
leave room.
