5 * Static tables for the Grand Unified Configuration scheme.
6 *
7 * Many of these tables are const. However, ConfigureNamesBool[]
8 * and so on are not, because the structs in those arrays are actually
9 * the live per-variable state data that guc.c manipulates. While many of
10 * their fields are intended to be constant, some fields change at runtime.
