Hi, Have a Query about ExecRemoteQuery. The logic seems to have been modeled after ExecMaterial. ISTM, that it should have been modeled after ExecScan because we fetch tuples, and those which match the qual should be sent up. ExecMaterial is for materializing and collecting and storing tuples. Can anyone explain? The reason for asking this is I am suspecting a big memory leak in this code path. We are not using any expression context nor we are freeing up tuples as we scan for the one which qualifies.
