I didn't submit a suggestion myself because I'm not clear on the actual circumstances. I know it won't be available if: - jit is not on in config - PG was not compiled with JIT support But does compilation with JIT enable and LLVM dev tools mean that all the LLVM compilation/optimization is built into the PG binaries, or does it require LLVM presence on the machine where deployed? And if so, does the function take that into account as well? I would guess the function is telling the truth under all circumstances, but I don't know for sure. Perhaps: "returns true if JIT (see Chapter 31) is available in this session. Availability of JIT requires that PG was compiled with JIT support, JIT is enabled in config, <blah blah blah is installed???>.
