No. You can test the speed of DropRelFileNodeBuffers() during normal operation, i.e. by running TRUNCATE on psql, instead of performing recovery. To enable that, you can just remove the checks for recovery, i.e. removing the check if InRecovery and if the value is cached or not. Regards Takayuki Tsunakawa
