This variable is the name of the JIT provider library to be used (see jit-pluggable). The default is llvmjit. This parameter can only be set at server start.
If set to a non-existent library, JIT will not be available, but no error will be raised. This allows JIT support to be installed separately from the main PostgreSQL package.
