First of all - it's not a bug - function works exactly as documented:
https://www.postgresql.org/docs/current/functions-formatting.html#FUNCTIONS-FORMATTING-DATETIME-TABLE
says:
"Day" -> full capitalized day name (blank-padded to 9 chars).
If you don't want the padding, use FM modifier, like:
select to_char('2020-01-31'::date,'FMDay');
