Обсуждение: JIT llvm11 package

Hi guys,

PostgreSQL 13.4 for SUSE linux  (should be same behavior on red hat)

_________________________________________________________

 

We installed the llvmJIT community RPM => postgresql13-llvmjit-13.4-1PGDG.sles15.x86_64.rpm   

=> It requires libLLVM11 : https://opensuse.pkgs.org/15.3/opensuse-oss-aarch64/libLLVM11-11.0.1-1.26.x86_64.rpm.html

=> Also requires llvm11 : https://opensuse.pkgs.org/15.3/opensuse-oss-aarch64/llvm11-11.0.1-1.26.x86_64.rpm.html

  

For llvm11  we faced a security issue for installation in production because this lib (llvm11) seems to be a kind of compiler.

So we installed *only* libLLVM11 (not llvm11) and tried the example test in JIT documentation : https://www.postgresql.org/docs/11/jit-decision.html  

it works...

 => Could you please confirm if this library is really needed: 'llvm11'  or we can  live only with 'libLLVM11' library installed and using PostgreSQL JIT feature 

 *without* any penalty on performances ?

Thank you very much

Best regards
