I guess the $64 question that has to be addressed here is whether we're
prepared to accept LLVM as a run-time dependency. There are some reasons
why we might not be:
* The sheer mass of the dependency. What's the installed footprint of
LLVM, versus a Postgres server? How hard is it to install from source?
* How will we answer people who say they can't accept having a compiler
installed on their production boxes for security reasons?
* Are there any currently-interesting platforms that LLVM doesn't work
for? (I'm worried about RISC-V as much as legacy systems.)
I concur with your feeling that hand-rolled JIT is right out. But
I'm not sure that whatever performance gain we might get in this
direction is worth the costs.
