I lowered the maintenance_work_mem to 50MB and am still getting the same errors: Oct 16 09:26:57 [16402]: [1-1] user=,db= ERROR: out of memory Oct 16 09:26:57 [16402]: [1-2] user=,db= DETAIL: Failed on request of size 52428798. Oct 16 09:27:57 [16421]: [1-1] user=,db= ERROR: out of memory Oct 16 09:27:57 [16421]: [1-2] user=,db= DETAIL: Failed on request of size 52428798. Oct 16 09:29:44 [16500]: [1-1] user=,db= ERROR: out of memory Oct 16 09:29:44 [16500]: [1-2] user=,db= DETAIL: Failed on request of size 52428798. Looking at my free memory (from TOP) I find Mem: 2062364k total, 1846696k used, 215668k free, 223324k buffers Swap: 2104496k total, 160k used, 2104336k free, 928216k cached So I don't think that I'm running out of memory total... it seems like it's continually trying to do it. Is there a reason why Postgres would be doing something without a username or database? Or is that just how autovacuum works?
