LGTM. Next, we can consider how to integrate context into the #[function] macro more gracefully. 🤔

[TennyZhuang]

@xiangjinwu PTAL

[xiangjinwu]

LGTM. Btw we would need to update this to detect such functions for a better experience.

risingwave/src/frontend/src/handler/query.rs

Lines 244 to 246 in f27182f

	fn must_run_in_local_mode(batch_plan: PlanRef) -> bool {
	SysTableVisitor::has_sys_table(batch_plan)
	}

[xiangjinwu]

We may need the function name in error message as well:

dev=> set query_mode to distributed;
SET_VARIABLE
dev=> select ''::regclass;
ERROR:  QueryError: Expr error: Context DB_NAME not found

Or maybe it can be part of any ExprError?

[TennyZhuang]

It should be a part of any ExprError

Unknown failure, seems unrelated to the PR.

must_run_in_local_mode

I know how to modify it. Just merge the PR first to make the future work
parallelizable.
