Failed to start with what error message, exactly? It sounds to me like
you are describing a problem with unreasonably low kernel parameters,
not with Postgres. (In particular I'd wonder what SEMMAX is on your
system, though I suppose SHMMAX might be the issue too. See the Admin
Guide concerning care and feeding of kernel parameters.)
