Sorry if I mislead you. I encountered this issue in the CREATE EXTERNAL TABLE statement as

datafusion/datafusion/sql/src/statement.rs

Lines 1017 to 1025 in 3773fb7

if !(&key.contains('.')) {
// If a config does not belong to any namespace, we assume it is
// a format option and apply the format prefix for backwards
// compatibility.
let renamed_key = format!("format.{}", key.to_lowercase());
options_map.insert(renamed_key, value_string.to_lowercase());
} else {
options_map.insert(key.to_lowercase(), value_string.to_lowercase());
}

How has such an issue typically been resolved previously? If adding a ParseOptions, e.g., enable_options_value_normalization, is a reasonable way to fix it, I could help there.

datafusion/datafusion/sql/src/planner.rs

Lines 97 to 100 in 47026a2

pub struct ParserOptions {
pub parse_float_as_decimal: bool,
pub enable_ident_normalization: bool,
}

I believe we can remove the lowercase conversion here and instead add it when we set ConfigField's (via alter_with_string_hash_map) for the cases where we can ignore case sensitivity.
