Try that first. If you still get an out of memory error, try setting enable_hashagg off (set enable_hashagg=false;) and then running the same query again and see if it then works. If it does, post the result of explain analyze YOURQUERYHERE If it doesn't post the output of a plain explain, no analyze. ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
