Hello I am looking on code in pl_exec.c file.
I see one issue: /* ---------- * exec_run_select Execute a select query * ---------- */ static int exec_run_select(PLpgSQL_execstate *estate, PLpgSQL_expr *expr, long maxtuples, Portal *portalP) { ParamListInfo paramLI; int rc; /* * On the first call for this expression generate the plan */ if (expr->plan == NULL) exec_prepare_plan(estate, expr, 0); .... rc = SPI_execute_plan_with_paramlist(expr->plan, paramLI, estate->readonly_func, maxtuples); if (rc != SPI_OK_SELECT) ereport(ERROR, (errcode(ERRCODE_SYNTAX_ERROR), errmsg("query \"%s\" is not a SELECT", expr->query))); .... } the test of rc is too restrict. I think so rc could be one from: SPI_OK_SELECT, SPI_OK_INSERT_RETURNING:, SPI_OK_UPDATE_RETURNING:, SPI_OK_DELETE_RETURNING - and errmsg "query %s doesn't return a table" with this change we can reuse this rutine and maybe little bit compress code.
