VACUUM FULL requires workspace proportional to the number of blocks in the table. You probably need to bump up the kernel's per-process memory limit (see ulimit and so on) if you want to VACUUM FULL such a large table. My advice: you shouldn't be using VACUUM FULL anyway. Quite aside from the memory issue, it's likely to take forever and a day. regards, tom lane
