Yeah. And IMHO this should be rejected entirely; there is no "date <= int4"
operator. If you dig into it you find that the parser is actually
interpreting the query as WHERE submit::text <= '1991'::text.
Apparently "text <= text" is the closest match it can find.
This is just another example of why allowing implicit coercions from
everything to text is a Bad Idea ...
