FWIW, there's no sizeof(void*) == 8 platform supported by PG where aligned 8 byte writes aren't atomic. There are a number of supported platforms with sizeof(void*) == 4 without atomic 8 byte writes though. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
