Can someone explain why LockMethodCtl is in shared memory while
LockMethodTable is in postmaster memory context?
I realize LockMethodCtl has a spinlock, so it has to be in shared
memory, but couldn't it all be put in shared memory?
Also, the code:
LockShmemSize(int maxBackends)
{
int size = 0;
size += MAXALIGN(sizeof(PROC_HDR)); /* ProcGlobal */
size += MAXALIGN(maxBackends * sizeof(PROC)); /* each MyProc*/
size += MAXALIGN(maxBackends * sizeof(LOCKMETHODCTL)); /* each
*
lockMethodTable->ctl */
Is there one LOCKMETHODCTL for every backend? I thought there was only
one of them.
