This is a post-review patch.
Fixes the typelib implementation, available only in 5.1.11.
--event-scheduler cmdline : DISABLED | ON | OFF | 0 | 1
DISABLED - makes the scheduler unavailable during the server run
(ON|1)- When the server is started the scheduler will be started. It can
be stopped and restarted by setting appropriate values to
GLOBAL event_scheduler
(OFF|0)- When the server is started, the scheduler won't be started. It
can be started and again stopped by setting appropriate values to
GLOBAL event_scheduler. _DEFAULT_ value
The GLOBAL variable event_scheduler can have the following values:
OFF | ON | 0 | 1
DISABLED is not possible and every attempt will end with an error that
it's not a valid value for the variable.
OFF | 0 - This is the pre-5.1.11 behavior - The scheduler stops, if not
already stopped, and can be started again by setting
the value of the variable to ON|1.
ON | 1 - This is the pre-5.1.11 behavior - The scheduler starts, if not
already started, and can be stopped again by setting the value
of the variable to OFF|0.
