The above is broken code, and always has been: the fact that it failed
to malfunction back in 7.4 was purely accidental.  You can only use the
syntax "typename literal" with a literal constant.  Instead of "date ?"
use "?::date", or if you want to be fully SQL-spec-compliant write it
out as "CAST(? AS date)".

Actually, it'd probably be better to use "date_trunc('day', ?)" anyway,
since that's what you're trying to achieve with the cast.
