## - The optimizer_switch system variable enables control over optimizer
## - behavior. The value of this variable is a set of flags, each of which
## - has a value of on or off to indicate whether the corresponding optimizer
## - behavior is enabled or disabled. This variable has global and session
## - values and can be changed at runtime. The global default can be set at
## - server startup.
