Then you could get a plan like I expect that the join produce about 4M rows, so I think the planner is wrong, and about the data, I already have the data and I preparing it for later processing, so I can't have any original source. I had also created and index inars_nocontrib_perm1_inx this way: create index inars_nocontrib_perm1_inx on inars_nocontrib_perm1 (ano,mes,cuil,cuit) but the planner didn't use it, as you can see. That's the way I broke the config file before (enable_seqscan=false). so this is my scenario, the query I need to do is this: update inars_nocontrib_perm1 set rectificada=TRUE,actividad=b2.actividad,presentacion=b2.presentacion,remuneracion=b2.remuneracionfrom inars_rectificacionesb2 where inars_nocontrib_perm1.cuil=b2.cuil and inars_nocontrib_perm1.cuit=b2.cuit and inars_nocontrib_perm1.ano=b2.anoand inars_nocontrib_perm1.mes=b2.mes; where inars_nocontrib_perm1 is about 35M rows inars_rectificaciones is about 10M rows sort memory 4096 based on your experience/calculation, could you give some advice, do I have to increase sort memory ? do I have to change the query ? ... well something, the query is running from about 28 hours, do I stop it and try something else ? is there anyway to check how long, even estimated, it will take to finish ? well thank's a lot for your help, I hope I'm not abusing of it, Best Regards, Pablo
