raw_value is only used in the error branch,introducing a redundant string allocation on the happy path.
How about excluding it from the error message?
let value = value.into_string().ok_or_else(|| {
plan_datafusion_err!("Typed literal requires a string payload")
})?;

Adjusted this to avoid the happy-path allocation in f416e71.
Guard SQL typed-literal planning against non-string payloads instead of panicking on unwrap. Add a regression test for the invalid TIME literal path reported in apache#21431. Signed-off-by: Asish Kumar <officialasishkumar@gmail.com>

Which issue does this PR close?
TIMEtyped literal causes planner panic #21431.Rationale for this change
Planning a malformed typed literal such as
time 17542368000000000currently panics indatafusion-sqlbecause the planner assumes everyTypedStringpayload is string-backed and callsinto_string().unwrap().Invalid SQL should surface as a normal planner error rather than aborting the planning path.
What changes are included in this PR?
unwrap()in theSQLExpr::TypedStringplanning path with explicit validation.TIMEtyped literal reported in the issue.Are these changes tested?
cargo test -p datafusion-sqlAre there any user-facing changes?
Users now receive a planner error for malformed typed literals instead of a panic.
