| Hello, My doubt here is, in a master - slave (streaming replication) set up, when I run a long running delete query for deleting 80 million records, . All queries in slave started running 2- 5 mins all of a sudden. When I check SQL analyse, most of the queries, planner used to choose seq scan, instead of seq scan. What could be the possibility? How delete query running in Master affect secondary(Slave) DB. Is it related to shared memory ? NB: Problem solved after restarting slave servers. Thanks Sreejith
