the possibility to control plan cache for any command via GUC outside PLpgSQL can introduce lot of question. What impact will be on PREPARE command and on EXECUTE command? If we disable plan cache for EXECUTE, should we remove plan from plan cache? ... Can we have some diagnostic to get info if some command has cached plan or not? Regards Pavel > > regards, tom lane >
