Not sure why that's happening. If this is a Linux box, maybe the permissions on /dev/shm are bollixed? As a temporary workaround, you could probably set dynamic_shared_memory_type = none in postgresql.conf (I'm assuming it's set to posix now). I do not think that disables any very critical functionality in 9.5, but it's a hack not a solution. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
