pgsql: Fix incorrect initialization of ProcGlobal->startupBufferPinWait - Mailing list pgsql-committers

Fix incorrect initialization of ProcGlobal->startupBufferPinWaitBufId.

It was initialized in the wrong place and to the wrong value.  With bad
luck this could result in incorrect query-cancellation failures in hot
standby sessions, should a HS backend be holding pin on buffer number 1
while trying to acquire a lock.
