this LLVM is >= 3.9 ? 

according to the docs : "Build with support for LLVM based JIT compilation  .... The minimum required version of LLVM is currently 3.9."

Hi Team,

The PG 12.2 server is crashing on setting the jit_above_cost param. Below is the output.

postgres=# select version();

                                                          version                                                           

----------------------------------------------------------------------------------------------------------------------------

 PostgreSQL 12.2 on x86_64-apple-darwin, compiled by Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn), 64-bit

(1 row)


postgres=# SET jit_above_cost=10;

SET

postgres=# SELECT count(*) FROM pg_class;

server closed the connection unexpectedly

This probably means the server terminated abnormally

before or while processing the request.

The connection to the server was lost. Attempting reset: Failed.
