I am not familiar with Alpine or any of the packaging and versioning
details over there, but I guess this is a basic version mismatch where
you're somehow using LLVM 16 libraries with a version of PostgreSQL
built for LLVM 15 or earlier. I'm working on updating PostgreSQL to
work with LLVM 16 at present (and starting to get close to sharing a
patch on the -hackers list) where we switch over to using
LLVMBuildGEP2 and other new C API changes with '2' bolted onto the
name, where you have to supply more type information when building IR,
but that'll only work for you if your PostgreSQL was actually built
against LLVM 16, so I think your problem is basic version mismatch.
You could simply turn jit off to avoid the error.
