Not recognize utils::datetime::Date as PostgreSQL date

[onpat]

Hi, I am using userver with PostgreSQL.

I made a table which consist of two fields, username(string) and birthday(date).
and tried this line:

auto res = transaction.Execute(kInsertRecord, "uname", userver::utils::datetime::Date(2000, 02, 03));

but I got this error at compile time:

/home/user/pg_service_template/src/test/user-register.cpp:364:35: required from here
/home/user/pg_service_template/third_party/userver/postgresql/include/userver/storages/postgres/detail/query_parameters.hpp:64:52: error: static assertion failed: Type doesn't have mapping to Postgres type.
64 | static_assert(io::traits::kIsMappedToPg || std::is_enum_v, "Type doesn't have mapping to Postgres type.");

/home/user/pg_service_template/third_party/userver/postgresql/include/userver/storages/postgres/detail/query_parameters.hpp:64:52: note: ‘(((bool)userver::v2_7_rc::storages::postgres::io::traits::kIsMappedToPguserver::v2_7_rc::utils::datetime::Date) || ((bool)std::is_enum_vuserver::v2_7_rc::utils::datetime::Date))’ evaluates to false
ninja: build stopped: subcommand failed.
make: *** [Makefile:32: build-debug] Error 1`

However, this document states utils::datetime::Date as date type.
