Log Message:
-----------
Restrict deadlock_timeout to the range for which the implementation
actually works sanely, viz not 0 and not more than INT_MAX/1000
(else TimestampTzPlusMilliseconds can overflow). Per discussion with
Greg Stark. Since this is a superuser-only setting and there was not
previously any big reason to change it, not worth back-patching.
