Log Message:
-----------
Detect early deadlock in Hot Standby when Startup is already waiting. First
stage of required deadlock detection to allow re-enabling max_standby_delay
setting of -1, which is now essential in the absence of improved relation-
specific conflict resoluton. Requested by Greg Stark et al.
