29.3. Configuration #
The configuration variable jit determines whether JIT compilation is enabled or disabled. If it is enabled, the configuration variables jit_above_cost, jit_inline_above_cost, and jit_optimize_above_cost determine whether JIT compilation is performed for a query, and how much effort is spent doing so.
Note
You cannot limit access between clusters on the HBA level.
For development and debugging purposes a few additional configuration parameters exist, as described in Section 18.19.
