4 The configuration variable jit determines whether JIT compilation is
5 enabled or disabled. If it is enabled, the configuration variables
6 jit_above_cost, jit_inline_above_cost, and jit_optimize_above_cost
7 determine whether JIT compilation is performed for a query, and how
8 much effort is spent doing so.
10 jit_provider determines which JIT implementation is used. It is rarely
11 required to be changed. See Section 30.4.2.
13 For development and debugging purposes a few additional configuration
14 parameters exist, as described in Section 19.17.
