As I understand it, LLVM is organized in such a way as not to require this. Andres, am I understanding correctly that what you're using doesn't require much of LLVM at runtime? > some people are going to complain, either because they are > trying to build little tiny machine images or because they are > subject to policies which preclude the presence of a compiler on a > production server.

Would you consider it solved if there were some very small part of the LLVM (or similar JIT-capable) toolchain added as a dependency, or does it need to be optional into a long future? > Unfortunately, that has the pretty significant downside that a lot of > people who actually want the postgresql-server-jit package will not > realize that they need to install it, which sucks.
