* Static tables for the Grand Unified Configuration scheme.
*
* Many of these tables are const. However, ConfigureNamesBool[]
* and so on are not, because the structs in those arrays are actually
* the live per-variable state data that guc.c manipulates. While many of
* their fields are intended to be constant, some fields change at runtime.
