select date '10000-1-1'< date '99991231'

return false.

If my database contains dates greater than DATE  '9999-12-31' then this
check fails.

This is why I'm searching for a real MAX_DATE value in Postgres.

It would be nice if there will be MAX_DATE constant in Postgres or some one
row system table contains MAX_DATE value.
