2017-04-15 04:31:21.657 GMT [16792] FATAL: could not reattach to shared memory (key=6280001, addr=0x7f692fece000): Invalid argument Presumably, this is the same issue we've seen on Windows where the shmem address range gets overlapped by code loaded at a randomized address. Is there any real hope of making that work? regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
