Hi, While working on [1], it is found that currently the ProcState array doesn't have entries for auxiliary processes, it does have entries for MaxBackends. But the startup process is eating up one slot from MaxBackends. We need to increase the size of the ProcState array by 1 at least for the startup process. The startup process uses ProcState slot via InitRecoveryTransactionEnvironment->SharedInvalBackendInit. The procState array size is initialized to MaxBackends in SInvalShmemSize. The consequence of not fixing this issue is that the database may hit the error "sorry, too many clients already" soon in SharedInvalBackendInit. Attaching a patch to fix this issue. Thoughts?
Thanks for making the patch! LGTM. Barring any objection, I will commit it. Regards, -- Fujii Masao Advanced Computing Technology Center Research and Development Headquarters NTT DATA CORPORATION
