ProcGlobalShmemSize() currently includes code to allow space for startupBufferPinWaitBufId. But I think that's redundant, because that variable is stored in PROC_HDR *ProcGlobal, for which this function is separately allocating space.
So I propose to apply the attached patch, barring objections. I see no reason to back-patch this, since allocating an extra 4 bytes of shared memory is hardly anything to get excited about. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
