What happens?

Hi,
if I apply normalize_names to /dev/stdin duckdb normalizes the field text to _text.

It should remain text.

To Reproduce

To reproduce

printf "name,text\nJohn,ipsum\n" | duckdb -line -c "select * from read_csv_auto('/dev/stdin',normalize_names=true);"

It gives in output

_name = John
_text = ipsum
